Document Summary
Thorn mimic need to be cryptic and not move (ex: tree hopper) Camouflaged looper: inchworms (most look like twigs but this one matches with the plant) add bits of debris. Woolly aphids (adding material contributes to camouflage) Scarlet lily lead beetle (secrete membrane around their body and when they excrete it goes all around their body) form of camo. Whirligig beetles half above water (black) and other half under water (white) bi-coloration: camouflage from two different directions. Aquatic insects have a dark side underside and white upper surface because they are back swimmers (swim upside down) White-tailed deer are also dark above and light below. Use their upper body to cover the lower body (countershading 3d to 1d to make it flatter and blending in) other ex: wolfs, sand pipers, rabbits. Self-shadow concealment: using a shadow to conceal. Sphinx moth (startle pattern modified into fake eyespots- deception) Gray tree frog has startle patterns (legs)
