Crab Spiders (Genus Mecaphesa), taken April 12, 2025, in Georgia, US

Some crab spiders hiding underneath flowers! This is a known undescribed species, currently labeled "black tibia spot" (for obvious reasons) as far as I know. I see them pretty often hanging out, especially on fleabane flowers like this. Crab spiders are ambush predators, and most in the genus Mecaphesa lie in wait on similarly-colored flowers until a prey item (flies, beetles, and perhaps small bees) lands on it. The spider quickly overtakes its prey and hides underneath the petals of the flower to enjoy. A rather boring life for us, but these guys don't seem to mind!
