Crab spiders are so called for resembling crabs when walking sideways or holding their front legs up to catch prey. They are generally well camouflaged with colors that match their hunting spots. Some species change colors over several days to match their new surroundings.
Crab spiders ambush and catch prey without a web. They often hide on flowers of the same color. Some hunt on the ground.
Crab spiders feed on insects such as flies. They are venomous to their prey and harmless to humans.
Although difficult to spot, crab spiders are common in vegetated areas and urban gardens.
