Who is immobilizing this bumblebee? Look closely as she is quite camouflaged!

This female Goldenrod Crab Spider is sucking up a meal! Like their namesake, crab spiders walk sideways and have wide and flat bodies with long front legs. Female Goldenrod Crab Spiders can change from white to yellow to white to match the flower on which they are hunting. These camouflaged crab spiders are ambush predators, sitting for days with their front legs held ready in a grasping position. Unlike web-spinning spiders, crab spiders have excellent vision. When a bee, fly, or other prey lands on a flower, the crab spider quickly injects venom to immobilize and digestive juice to dissolve their meal.

Goldenrod crab spiders’ default color is white. It can take 10-25 days to change to bright yellow, but only about a week to change back to white.
