What are the differences between bugs and beetles?. Well I’d never really thought about it (as most people refer to “Bugs” as any insect or spider). But I ran into problems reseaching Harlequin Beetles because… they are actually Bugs
Here is how to tell.
Bugs: mouthparts modified into piercing stylet (i.e. needle-like).
Beetles: chewing mouthparts.
Bugs: wings (if present) are membranous or partially thickened.
Beetles: forewings modified to form hard, leathery coverings called elytra, hindwings membranous and fold under elytra when not flying.
Bugs: liquid diet: mostly plant-feeders (nectar/sap), some feeders on animal fluids.
Beetles: wide range of plant and animal materials eaten.
Bugs: incomplete metamorphosis – juveniles resemble adults except smaller and lack wings.
Beetles: complete metamorphosis – larvae with hardened head, chewing mouthparts and usually have legs.
Bugs: Order Hemiptera
Beetles: Order Coleoptera
