A Ground Crab Spider

While most of us expect crab spiders to be hunting on or near flowers, many in the Xysticus genus of the Thomisidae hunt on the ground, where I found this specimen.

Male Elegant Spider, Xysticus elegans

Male Ground Crab Spider, Xysticus sp. (probably X. elegans)

A ground crab spider from Writing-on-Stone Provincial Park, southern Alberta.

Identified through the Alberta Spiders website (website by R. Bercha and R. Leech) and  BugGuide.

(Email communication with Robin Leech indicates that an exact I.D. cannot be made without a close view of ventral portion of the palps.)

    ooh, VERY cool. I love crab spiders and didn’t know about the ground version, thereof. And suitably tinted, eh? Very earth tone.

    I think to get a picture of the underside of the palps you’d have to ask verrrrry nicely. =)
