[The experiment showed] that all bed bugs—males, females, old and young alike—avoid wet surfaces. [Smaller], younger bed bugs make a faster U-turn when they realize they're approaching a wet surface, showing the younger insects are more sensitive to water and dampness.

Tropical feedback loop: Butterfly mimicry patterns evolve faster near the equator
[If] one of your competitors was an Olympian speed runner, you'd quickly conclude that your time would be best spent chasing after some of the slower players. If there were multiple Olympian [runners, by wearing the same uniform they could implicitly tell] you not to bother trying to catch any of them.

Harvestmen arachnids apparently use fluorescent patterns for species recognition
Five closely related species show species-specific, strongly fluorescent structures on their backs that become especially visible under ultraviolet light. The results suggest that these patterns serve for species recognition—particularly at dusk and in moonlight.
