Tiny White Flower With Defensive Yellow Crab Spider Stock Image

Crab spiders are carnivorous, feeding on invertebrate insects such as flies, bees, butterflies, grasshoppers, dragonflies, and hoverflies. Bumblebees, Bombus appositus, provide the spider with the most biomass, but small syrphid flies Toxomerus marginatus. The yellow pigments are kynurenine and 3-hydroxykynurenine. Color changes are induced by visual cues and spiders with impaired vision lose this ability. Notably, spiders of this species sometimes choose to hunt on flowers that, to the human eye, they do not appear to match in color. Very hard to see.
