Goldenrod crab spiders look a little like miniature crabs, hence the name, and sometimes hold their large front legs curved in front of their heads in a crab-like pose. Goldenrod crab spiders are ambush predators, meaning they don’t spin webs to capture prey. Instead, they lie in wait on flowers. When a bee, fly, or other pollinating insect lands on the flower seeking nectar, the crab spider attacks, grabbing the prey, injecting venom (fatal to insects, numbing them within seconds) and then drinking its juices.
