Discoid Roaches vs. Hornworms: A Keeper's Honest Comparison

I've kept feeder colonies and bought variety feeders for years, and the question I get more than almost any other is some version of "roaches or worms?" Usually it's discoid roaches versus hornworms specifically, because those two are the cleanest, most beginner-friendly feeders on opposite ends of the spectrum: one is the protein-dense workhorse you breed at home, the other is the water-rich treat you buy by the cup. People want to know which one to feed their bearded dragon, their leopard gecko, their chameleon — as if it's an either/or.

It usually isn't. But the differences between them are real, specific, and worth understanding, because matching the right feeder to the right animal and the right moment is most of what good nutrition actually is. This is the honest, side-by-side breakdown: what each one is, how they compare on every nutrition axis that matters, what it takes to keep each, what they cost over a year, which animals each suits, and a clear verdict at the end. I'll correct a few things that get repeated incorrectly all over the internet along the way.

The short answer, up front

If you only read one paragraph: discoid roaches are a staple, hornworms are a supplement. Discoids carry the protein and energy that build and maintain an animal, they breed at home so they're nearly free over time, and a colony runs itself. Hornworms are mostly water — fantastic for hydration, irresistible to picky eaters, and gentle on digestion, but far too low in protein to anchor a diet, and impossible to breed practically at home. The best diet for most insectivores uses a staple roach plus hornworms rotated in a couple times a week. Read on for exactly why, and for the cases where the balance shifts.

What discoid roaches actually are

Discoid roaches (Blaberus discoidalis) are a tropical roach native to Central and South America, in the family Blaberidae. Adults reach about 1.5–2 inches, with a flattened, oval, glossy body that runs tan to brown with subtle darker markings. They go through incomplete metamorphosis — egg, nymph, adult — so nymphs look like small wingless adults and molt their way up over several months, getting larger and darker with each molt.

Here's the first correction, because it's wrong nearly everywhere: adult discoids do have wings. Males carry longer wings that extend past the abdomen; females' wings lie shorter and flush. What's true is that they're poor flyers — they don't take off and cross a room the way a cricket leaps or a pest roach scatters. So "flightless" in the practical sense is fair, but "wingless" is simply incorrect, and it matters because the wings are how you sex them.

The trait that makes discoids so forgiving as a feeder is that they can't climb smooth vertical surfaces. A plain plastic bin contains adults with no sealed lid and no barrier around the rim. (They can grip rough surfaces like cardboard and screen, which is why nymph escape-proofing still matters — more on that in the keeping section.) They're nocturnal, shy, and a bit burrow-prone, which also makes them easy for an animal to catch once they're tipped into an enclosure.

In the wild, discoids are decomposers living on warm, humid rainforest floors, eating decaying plant matter and fallen fruit. That ecology is the whole care sheet: warm, humid, dark, fed on plant matter and grain. Everything about keeping them is just recreating a patch of South American forest floor in a bin. For deeper husbandry, I've written a full discoid roach keeping and breeding playbook; the keeping section below is the condensed version.

What hornworms actually are

Hornworms are not worms at all — they're the larvae (caterpillars) of the hawk moth, specifically Manduca sexta, the tobacco hornworm. They're the big, soft, vivid-green caterpillars with a harmless horn-like spike at the tail. In the wild they devour plants in the nightshade (Solanaceae) family — tomato, tobacco, potato leaves — and they eat with such appetite that they can strip a tomato plant, which is exactly why gardeners hate them and reptile keepers love them: they convert food into body mass astonishingly fast.

That speed is the defining fact about hornworms. Their whole life cycle — egg to larva to pupa to moth — runs in a matter of weeks, and a feeder-sized hornworm can grow from a few millimeters to four inches in well under two weeks at warm temperatures. You are buying them in a brief window of their life and racing the clock to use them before they outgrow your animal.

Here's the second correction, because the toxicity warning is constantly stated without the crucial qualifier: commercially raised hornworms are safe and are not toxic. Wild hornworms feeding on tobacco or tomato accumulate plant alkaloids that can poison a reptile, which is a genuine reason to never feed wild-caught ones. But feeder hornworms are reared specifically on a non-toxic, nutritionally controlled gut-load chow (often a wheat-germ-based diet) precisely so they don't carry those compounds. Buy from a real feeder supplier and the toxicity issue disappears. The risk is wild-collecting, not the species.

The other defining fact is water. A hornworm is roughly 85% moisture — it is, functionally, a hydration delivery system with a little protein attached. That single number drives almost every pro and con that follows.

Nutrition head-to-head

This is the section that should actually decide most of your feeding choices, so let me lay the numbers out plainly and then explain what they mean. Treat these as approximate, as-fed figures — real values swing with diet, life stage, and source — but the relationships between the two feeders are reliable, and those relationships are what should drive your decisions.

Protein: the staple-versus-treat divide

Protein is where these two feeders separate most dramatically, and it's the single reason discoids are a staple and hornworms aren't. Discoid roaches run around 20% protein as-fed (often cited up to 22–23% on a dry-matter basis), which is genuinely high for a feeder insect and supports growth, tissue repair, muscle development, and the high metabolic demands of juveniles and breeding animals. You can feed a modest number of roaches and deliver real, dense nutrition.

Hornworms come in around 9% protein as-fed. You'll occasionally see higher numbers quoted (16–20%), but those are dry-matter figures, and quoting them next to an as-fed moisture number is how the internet ends up contradicting itself. On an apples-to-apples as-fed basis, a hornworm is a low-protein food. That isn't a flaw — it's just what it is. A hornworm-heavy diet leaves most insectivores chronically short on protein, which shows up over months as poor growth or condition. Hornworms feed the animal's hydration and palatability needs, not its protein needs.

Fat: lean both ways, leaner for hornworms

Neither of these is a fatty feeder, which is part of why both are "healthy" reputations. Discoids sit at a moderate ~6–7% fat (some sources push 8–10%), enough to provide steady energy without the obesity and fatty-liver risk you get from genuinely fatty feeders like superworms (~15% fat). Hornworms are leaner still at ~3%. For an animal prone to obesity, a sedentary adult, or a species that needs a low-fat diet, that leanness is a real point in the hornworm's favor — but it comes paired with the low protein and high water, so a lean hornworm isn't a substitute for a lean staple; it's a lean supplement.

Moisture and hydration: the hornworm's superpower

This is the category hornworms exist to win. At ~85% water, a hornworm is one of the best hydration tools you can hand a reptile that isn't drinking enough. For desert and arid-adapted species that come into a vet for dehydration, for an animal recovering from illness, for a chameleon that drinks from movement and moisture rather than a bowl, or for a constipated/impacted animal that needs gentle help moving things along, hornworms are close to medicinal. I keep them on hand specifically as a hydration and "get-things-moving" tool.

Discoids, at ~60% moisture, are not a hydration food — and that's fine, because a feeder that's mostly water is also mostly not nutrition. The flip side of the hornworm's hydration is dilution: you have to feed a lot of hornworm to deliver a little protein. For an animal with high nutrient demand, that concentrated-versus-diluted trade-off is the whole story. And the same water that helps a dehydrated animal can give a moisture-sensitive, desert-adapted reptile loose stool if you overdo it.

Calcium, phosphorus, and the ratio that actually matters

Here's the third and most important correction, because the source material on this topic routinely contradicts itself — calling discoids' calcium ratio "favorable" in one breath and a problem in the next. The truth is clean and worth memorizing:

Discoid roaches, like nearly every feeder insect, have a poor (inverted) calcium-to-phosphorus ratio — roughly 1:3, phosphorus-heavy. That is why you dust roaches with a calcium supplement before feeding. It's not optional; an undusted roach diet drives reptiles toward metabolic bone disease (MBD), the calcium-deficiency disease that deforms and weakens the skeleton. Gut-loading helps, but it does not fix the underlying ratio.

Hornworms have a genuinely good calcium-to-phosphorus ratio — around 1.5:1, calcium-favorable — which is unusual and valuable among feeders. This is the second category hornworms clearly win, and it pairs naturally with their role for animals that need a calcium boost. You should still dust most feeders as a habit, but a hornworm starts from a far better baseline than a roach does.

So if you've ever read that discoids have a "favorable" calcium ratio, scrub it from memory. They're a fine staple — but on calcium specifically, you supplement to compensate, while the hornworm comes closer to right out of the cup. The proper handling of calcium and phosphorus in feeder insects is exactly the kind of thing university extension entomology programs document well; the University of Florida's Entomology and Nematology Department is a solid non-commercial starting point for feeder-insect and invasive-species information.

Chitin and digestibility: both gentle, hornworms gentlest

Chitin is the hard material in an insect's exoskeleton. Too much of it is hard to digest and, in small or young animals, contributes to impaction (a dangerous gut blockage). Discoids have a relatively low chitin content compared with crickets or mealworms — their softer shell is one of their best traits, making them easy to digest across a wide range of animals. Hornworms have essentially no meaningful exoskeleton; they're soft all the way through, which makes them the single most digestible feeder you can offer. That's why hornworms are a go-to for juveniles, for species with sensitive digestion, and for any animal you're worried about impacting.

The nuance the source overstates: it warns about "chitin overload" from discoids causing blockages. In practice, discoids are low-chitin and rarely an impaction risk when you size them correctly — the impaction warning belongs much more to hard-bodied feeders like adult mealworms and superworms than to discoids. Size the feeder to the animal (no wider than the space between the eyes is the classic rule) and a discoid is gentle. A hornworm is gentler still.

Keeping discoid roaches

The headline advantage of discoids is that you can keep and breed them, turning a one-time purchase into a near-permanent supply. The condensed setup:

• ◆Bin: an opaque plastic storage tub. Dark keeps them calm and breeding; plastic is cheap and takes side-mounted heat well. A 10-gallon-equivalent bin holds a starter colony of ~100.
• ◆Furniture: cardboard egg flats stood vertically. They triple the usable surface area, give nymphs dark hiding spots, and make harvesting a matter of lifting a flat and shaking off what you need.
• ◆Ventilation: cut windows in the lid and high on a side wall for cross-flow, then cover every opening with fine metal mesh hot-glued in place. Adults can't climb smooth walls, but pinhead nymphs walk straight through drilled holes or coarse screen. This one detail is the difference between zero escapees and finding roaches in the room.
• ◆Heat: this is the lever that decides everything. Discoids survive at room temperature but only breed in a hot, narrow band — target 85–90°F (29–32°C) in a warm zone. Mount the heat mat on a side wall, never the bottom (bottom heat cooks the substrate zone where they cluster), and always run it through a thermostat. A sluggish colony is almost always a cold colony.
• ◆Humidity: 60–70%, via a water-crystal dish (also their drinking water, no drowning risk) or a damp sponge. Too dry stalls nymphs; too wet invites mold and grain mites.
• ◆Diet (gut-loading): a dry protein base always available, plus rotated produce — carrots, squash, sweet potato, leafy greens, apple. For 24–48 hours before you feed off, load them with good produce so the roaches your animal eats are packed with nutrients.
• ◆Patience: nymphs take ~4–6 months to mature, and discoids breed slower than dubia. Start bigger than feels necessary and leave the colony alone for the first few months while it builds.

Discoids are live-bearers — females carry the egg case internally and give birth to live nymphs — so there's no fragile egg case to dry out and no incubation to manage. Set it up right and a colony becomes the most boring, self-sustaining thing in the animal room, which for a feeder is exactly the goal.

Keeping hornworms

Keeping hornworms is a completely different job, and the honest framing is: you don't really keep them, you race them. You're not maintaining a colony; you're holding a perishable, fast-growing larva for a couple of weeks until you feed it off.

Hornworms ship and are sold in a plastic cup with the gut-load chow already smeared on the lid or floor — the larvae hang from the underside and eat upward. Your whole maintenance job is:

• ◆Control the temperature to control growth. At 82–85°F hornworms grow explosively and will outgrow your animal in days; held cooler at 60–65°F, they slow way down and your supply stretches for a couple of weeks. Never refrigerate them — cold below the low 50s kills them outright. Room temperature on a cool shelf is usually about right.
• ◆Keep the cup clean and dry-ish. Pull out frass (droppings) and any dead larvae, and remove anyone that's started to pupate or darken. Condensation and mess in the cup will rot the colony fast.
• ◆Don't try to feed them yourself. They need the specific non-toxic chow; tossing in tomato or random greens defeats the safety of the commercial diet and can reintroduce the toxicity problem. If you must extend them, you buy more chow, but for most keepers that's not worth it.
• ◆Use them while they fit. A hornworm that's grown past the width of your animal's mouth is a choking/impaction risk and is wasted. Buy a quantity you'll actually use in two weeks.

Breeding hornworms at home is technically possible but practically pointless for a pet keeper: you'd need to let larvae pupate, hatch into moths, mate the moths, collect eggs, and maintain the controlled diet through it all. It's a science-lab workflow — Manduca sexta is, in fact, a classic laboratory model organism for exactly this reason — not a reptile-keeping one. For a pet keeper, hornworms are a buy-as-needed item. When I need them, I order them sized appropriately from a feeder supplier that raises them on proper chow, like All Angles Creatures' hornworms, and use the cup up within its window rather than trying to culture them.

Cost over a year

This is where the staple-versus-supplement nature of each feeder turns into dollars, and the gap is large.

Discoid roaches are cheap over time because you stop buying them. A starter colony runs roughly $20–60 depending on size, and that's essentially the whole cost. Once it's producing, the colony replenishes itself for the price of vegetable scraps and a little roach chow. Feed a single bearded dragon and a healthy colony will outproduce its appetite indefinitely. The upfront work (the bin, the heat, the wait) is the price; the payoff is a feeder line that approaches free.

Hornworms cost money every single time because you can't breed them. They sell for about $10–30 per cup of 10–25 worms, and since culturing them isn't realistic, that cost recurs with every order. They also have a wastage tax: buy too many or let them get warm and they outgrow your animal before you can use them, so you're throwing away part of what you paid for. Shipping matters too — they're perishable and need careful packaging, especially in temperature extremes.

The math is straightforward: as a staple, hornworms are expensive and discoids are nearly free. As a treat fed twice a week, hornworms are perfectly affordable — a cup stretches across several feedings, and you're buying them for a job (hydration, palatability, calcium) that roaches can't do anyway. The cost argument isn't "roaches win," it's "use each one for what it's cost-effective at."

Which animals suit which feeder

The right answer is almost always "both, in the right proportion," but the proportion shifts by species. Here's how I actually feed the common ones:

• ◆

  Bearded dragons. Discoids as the insect staple, especially for fast-growing juveniles that need protein several times a day. Hornworms a couple times a week as a hydration treat, to tempt a dragon that's gone off its food, or as a soft meal during shed. Beardies love hornworms — sometimes too much, so don't let them hold the diet hostage. Always dust roaches with calcium.

• ◆

  Leopard geckos. Discoids sized small-to-medium (no longer than the space between the eyes) make an excellent staple; their slower movement suits a gecko that isn't a frantic hunter, and their low fat helps with weight management. Hornworms in moderation as a treat and for the occasional hydration or constipation assist. Watch sizing closely — leopard geckos can be enthusiastic and a too-large feeder is a real risk.

• ◆

  Crested geckos. Their diet is anchored by a complete powdered crested-gecko diet, so insects are supplemental either way. Small discoids once or twice a week add protein and enrichment; the occasional hornworm is a treat. Neither is a staple here because the powdered diet is.

• ◆

  Chameleons. This is the species where hornworms shine brightest. Chameleons are prone to dehydration, drink from movement, and respond hugely to the hornworm's vivid color and wriggle — it's one of the best appetite-stimulating, hydrating feeders for them. But protein still has to come from elsewhere, so chameleons get a varied staple (discoids among them, appropriately sized) with hornworms as a regular hydrating treat.

• ◆

  Larger frogs and toads (Pacman frogs, large toads). Adult discoids and large nymphs as a protein staple; these animals will overeat, so watch body condition. Hornworms are a great soft, hydrating change-up but their water content means they're filling without being nourishing — don't let a Pacman frog turn into a hornworm vacuum.

• ◆

  Monitors and tegus. Big carnivores with flexible diets. Discoids are a useful protein item within a varied diet built largely on whole prey and other proteins; for large individuals, insects of any kind are a supplement to bigger food. Hornworms are a minor, occasional item here — they simply don't deliver enough per worm to matter much to a large monitor.

The universal rules across all of them: size the feeder to the animal, dust appropriately (calcium on roaches especially), and rotate variety in. Both feeders' soft bodies make them safe across this whole range.

Use cases: when to reach for which

Stepping back from species, here's the decision framed by situation, which is how I actually think about it at feeding time:

Reach for discoid roaches when:

• ◆You need a daily/regular staple that builds and maintains the animal.
• ◆You want to control feeding costs by breeding at home.
• ◆The animal needs concentrated protein — juveniles, breeders, anything growing.
• ◆You want a quiet, low-odor, escape-resistant feeder you can keep in bulk.

Reach for hornworms when:

• ◆The animal is dehydrated, in arid conditions, or recovering from illness.
• ◆You're fighting constipation or a mild impaction and want gentle, moist help.
• ◆A picky eater or an animal off its food needs tempting — the color and movement are hard to resist.
• ◆You need the softest possible feeder for a juvenile or a sensitive digestive system.
• ◆You want a low-fat, calcium-favorable treat to round out a diet.

Used this way they're not rivals at all — they're two tools for two jobs. The mistake is asking one to do the other's job: a hornworm-only diet starves an animal of protein, and a roach-only diet (without hydration variety and without dusting) misses hydration and calcium.

Risks and how to avoid them

Both feeders are safe when handled correctly. The realistic risks, and the fixes:

Discoid roach risks.

• ◆Inverted calcium ratio. The real one. Their ~1:3 Ca:P means undusted roaches push toward metabolic bone disease over time. Fix: dust with calcium (and calcium-plus-D3 or a multivitamin on schedule), and gut-load well.
• ◆Pesticide carry-over. A poorly raised colony can carry chemical residues. Fix: source from a clean, transparent supplier and never feed produce that's been sprayed.
• ◆Escape. Overstated for adults (they can't climb smooth walls and don't fly well), real for nymphs through coarse vents. Fix: fine metal mesh on every opening.
• ◆Impaction from oversizing. Any feeder too large is a risk. Fix: size to the animal. Despite what you'll read, discoids are low-chitin and not a notable impaction risk when sized right.

Hornworm risks.

• ◆Wild toxicity. Wild hornworms on tomato/tobacco accumulate toxic alkaloids. Fix: only ever feed commercially raised hornworms reared on non-toxic chow. Never wild-collect.
• ◆Overhydration / loose stool. In desert-adapted, moisture-sensitive species, too many hornworms cause diarrhea. Fix: feed as a treat, not a staple, and watch stool quality.
• ◆Outgrowing the animal. They grow explosively in warmth and can become a choking hazard. Fix: keep cool (~60–65°F) and use them while they fit.
• ◆Dietary monopoly. Their color and softness make them so appealing that some animals start refusing other feeders. Fix: don't over-offer; keep them an occasional item so the animal stays on a varied diet.

The common thread: discoid risk is mostly about supplementation and containment, hornworm risk is mostly about sourcing, sizing, and moderation.

Feeding mechanics and enrichment

How a feeder behaves in the enclosure matters more than people expect, because feeding is one of the few genuine sources of mental and physical enrichment a captive reptile gets. The two feeders here trigger completely different instincts, and that's a feature you can use deliberately.

Discoid roaches move in a slow, ground-level, slightly burrowing way. Dropped into an enclosure they'll head for cover, which makes a reptile hunt — track, stalk, dig, and chase at a low intensity. For geckos, monitors, and other ground hunters, that low-and-slow prey movement is close to what they'd encounter naturally, and it rewards foraging behavior without overstimulating the animal. You can lean into this by scattering roaches across the substrate or tucking them near hides rather than dropping them in a bowl, turning a meal into a few minutes of natural behavior. The flip side: a roach that finds deep substrate and burrows in can be missed and die in the tank, so in heavily planted or deep-substrate setups, tong-feeding or a shallow feeding dish keeps things accountable.

Hornworms do the opposite. They barely move — a slow, conspicuous wriggle — but their vivid green color and soft body are a powerful visual trigger, especially for sight-driven hunters. For chameleons and other arboreal species, a hornworm clipped to a branch or offered on tongs invites a climbing, striking, tongue-projecting response that's both great exercise and unmistakably satisfying to watch. Their slow movement and squishy texture also make them the feeder of choice for animals that hesitate with fast or hard prey: hatchlings learning to hunt, recovering animals rebuilding appetite, and picky individuals that have decided crickets are beneath them.

Used together, the two feeders give you two different enrichment levers — a ground-hunting workout from roaches and a strike-and-climb stimulus from hornworms — which is one more reason a rotation beats a monoculture. Varying not just what you feed but how you present it keeps an animal mentally engaged across the week.

Sourcing, shipping, and quarantine

Where you buy matters more for these two feeders than almost any other husbandry choice, and the considerations are different for each.

For discoid roaches, the goal is healthy founding stock for a colony you'll keep for years, so a bad source haunts you. Look for active, glossy roaches across a range of sizes — a spread of adults and nymphs reaches steady production far faster than a batch of all-same-size individuals, which can take months before any are mature enough to breed. Buy from a supplier that keeps clean colonies; weak, mite-ridden, or mixed-up starter stock imports problems you'll spend months fixing. When you add new roaches to an established colony, quarantine them in a separate bin for a couple of weeks first and watch for grain mites, mold, or die-offs before merging. It's a small step that prevents seeding a pest problem into a thriving colony. Because discoids are a one-time-ish purchase, it's worth paying for quality up front.

For hornworms, you're buying a perishable, fast-growing larva, so the priorities shift to freshness, diet, and shipping. Confirm they're raised on proper non-toxic chow — that's the safety guarantee that separates feeder hornworms from dangerous wild ones. Buy them small to medium unless you specifically need large worms, because they grow so fast that a "medium" cup can be "too big for my gecko" within a week. Hornworms are temperature-sensitive in transit: heat cooks them and cold kills them, so suppliers ship with care and you should avoid ordering into extreme weather or letting a delivered cup bake on a porch. Inspect a new cup for condensation, mold, dead larvae, or anyone already darkening toward pupation, and clean it out on arrival. Because you'll reorder hornworms regularly, a reliable supplier with consistent sizing and clean chow is worth sticking with.

The underlying difference is the same one that runs through this whole comparison: with discoids you're making an investment in a living system, with hornworms you're buying a consumable on a clock.

A sample weekly feeding plan

To make the staple-plus-supplement idea concrete, here's roughly how I'd run a week for a healthy juvenile-to-adult bearded dragon — the most common animal this question comes up for. Adjust quantities to your animal's size and appetite, and treat this as a template rather than a prescription.

• ◆Daily: appropriately sized discoid roaches as the protein staple — for a fast-growing juvenile, as many as it'll take in a 10–15 minute window, once or twice a day; for an adult, a smaller portion every other day as it shifts toward more greens. Dust roaches with plain calcium at most feedings.
• ◆Greens: offered daily and refreshed, independent of the insects — the plant side of an omnivore's diet that neither feeder replaces.
• ◆Two days a week: swap or supplement with hornworms as a hydration-and-variety treat — a few worms in place of part of the roach portion. Great on shed days and any day the animal seems sluggish about eating.
• ◆Supplement schedule: plain calcium most days as above, with a calcium-plus-D3 or multivitamin a couple times a week depending on your lighting and species needs.
• ◆Watch and adjust: track stool quality (loose stool may mean too many hornworms), body condition (lean toward greens and roaches, away from treats, if an adult is gaining), and appetite (lean on hornworms' palatability if an animal goes off its food).

The same skeleton works for other insectivores — anchor on the staple roach, keep greens or a complete diet going where the species needs it, and rotate hornworms in for their specific jobs. The plan does in practice what the verdict says in theory: roaches build the animal, hornworms fill the gaps.

The verdict

After years of feeding both, my call is unambiguous and it isn't really a contest — because they're not competing for the same job.

Discoid roaches are the better feeder for the role most keepers actually need filled: a staple. They carry the protein and energy that build an animal, they're low-fat and low-chitin and easy to digest, they breed at home so they're nearly free over time, and a colony is quiet, odorless, and self-sustaining. If you keep an insectivore and you're going to maintain one feeder, make it a staple roach. For most southern-US keepers — where dubia are restricted but discoids are accepted — discoids are the obvious staple choice.

Hornworms are the better feeder for the jobs a staple can't do. Their ~85% moisture makes them a near-medicinal hydration tool, their calcium-favorable ratio is genuinely useful, they're the softest and most digestible feeder available, and their color and movement tempt animals that won't eat anything else. But their low protein and inability to breed at home mean they're an expensive, perishable supplement — never a foundation.

So don't pick one. Build the diet on discoid roaches and rotate hornworms in a couple of times a week for hydration, variety, and the situations above. That combination — concentrated protein staple plus water-rich, calcium-favorable treat — covers what either one alone leaves out, and it's exactly how a healthy insectivore should be fed. The "versus" framing sells the question short; the real answer is "both, on purpose."
