Ladybug larvae look nothing like adults — they're long, segmented, and black with orange spots. Most people kill them as pests by mistake.
Desert locusts have two completely different forms — calm solitary green grasshoppers transform into yellow-and-black gregarious swarmers when crowded.
The transformation is triggered by serotonin — high serotonin levels in crowded locusts rewire color, behavior, and metabolism.
Hercules beetle wing covers change color from yellow to black with humidity — the mechanism is studied as a model for adaptive smart materials.
Orchid mantises can shift body color from white to pink over several molts to match local flower populations.
Domesticated silkworm moth adults cannot fly — 5,000 years of selective breeding stripped the ability.
As a walking leaf ages, its body color changes to match older, browner foliage — the mimicry tracks the seasons.
