A camouflaged Crab Spider (Family Thomisidae) kills a bee in a pinkish magenta thistle flower on the hike to Rachel Lake in Alpine Lakes Wilderness Area, Washington, USA. Crab Spiders can change their coloration to match the flower within 24 hours. They are widespread in Washington and other states. Spiders have eight legs and are not insects. Spiders (order Araneae, class Arachnida) are air-breathing arthropods that have chelicerae, grasping mouthparts with fangs that inject venom. Unlike spiders, insects have six legs and a pair of antennae.
