Crab Spider Diseases

Crab spiders, Family Thomisidae, are named for their close resemblance to crabs. The front legs of crab spiders are longest, and many crab spiders move sideways rather than backwards and forwards, giving them a crablike movement. Their bodies are also flat like a crab’s.

Crab spiders are best known for their unique ability to blend in with their surroundings. Some species change colors and some exhibit markings that resemble specific plants. Some species appear like blades of grass, while others may blend in with the bark of trees.

Crab spiders are not known to transmit diseases to humans. Although crab spiders are venomous spiders, their bite is considered relatively harmless to humans. However, if medical concerns arise, medical attention should be sought.
