Fireflies aren't flies — they're beetles. The order is Coleoptera, family Lampyridae.
Atlas moths lack a complete digestive system as adults — there's nothing for food to go through, even if they could eat.
Adult human botflies cannot bite. They have no functional biting mouthparts at all.
Brown recluses have six eyes (not eight, like most spiders) — arranged in three pairs.
The death's-head hawkmoth has a clear human skull pattern on its thorax — coincidence of natural pattern, not deliberate mimicry.
Despite the name 'centipede' (Latin: 100 feet), no centipede actually has 100 legs — counts are always odd-paired numbers like 21, 23, or 47.
Glasswing butterfly wings are transparent — you can read text through them.
