Thomisidae & Family Philodromidae
Size: Body is usually less than 1/2-inch in length, but
up to one inch in larger species.
Color: The crab spider’s color varies, but most species
are brown. Some are brightly colored in yellow, green or even pink,
depending on the type of flower they frequent.
Crab spiders are passive hunters that ambush their prey. These
spiders wait patiently on plants and flowers for flies, bees,
butterflies and other insects to visit, and then they pounce upon
the unsuspecting insect.
Habitat – These spiders prefer to stay outside;
they are rarely seen inside. On occasion a single spider will wander
into a building searching for prey, or it could be carried inside in
potted plants or fresh cut flowers.
Tips for Control – Crab spiders are not
dangerous and are not considered a “home pest.” If you find a
single crab spider indoors, you can easily capture and release it.
Place a cup over the spider and then slide a piece of paper
underneath to trap it within the cup. Turn the cup over while
holding the paper tightly over the top. Take the spider outdoors to
