"Crab spider on a thistle in Big Cypress National Preserve"

WILDLIFE PHOTOGRAPHY – BIG CYPRESS WMA, FL

This photo of a crab spider on a purple thistle was taken in the Big Cypress National Preserve usung a Nikon D90 and Nikkor 60mm lens.

Crab spiders or Thomisidae family of the Araneae order. They are called crab spiders because they resemble crabs, with two front pairs of legs angled outward and bodies that are flattened and often angular. Also, like crabs, Thomisidae can move sideways or backward.

Crab spiders do not build webs to trap prey, but are hunters and ambushers. Some species sit on or among flowers, bark, fruit or leaves where they grab visiting insects. Individuals of some species, such as Misumena vatia, are able to change color to match the flower on which they are sitting. Other species, with their flattened bodies, hunt in the crevices of tree trunks or under loose bark. Members of the genus Xysticus hunt in the leaf litter on the ground. In each case, crab spiders use their powerful front legs to grab and hold onto prey while paralyzing it with a venomous bite.

  1. That is a crazy looking crab spider! I agree the flower is a much better sight than the spider. I have had a giant crab spider in my backyard and they are gross, at least this one looks pretty on the flower.

  2. Alan, I love these crab spiders. I have watched them for hours, catching all sorts of things, including a bee. It was way bigger than the spider but caught nevertheless. My favourites are those that live on the white flowers that blossom only in the spring/summer here in Australia. They appear like little white miracles when the flower bloom and before that, they are brown – like the rest of the bush.
    Your photography is awesome. I love it very much.
