Miturgidae and Mimetidae

Cheiracanthium sp.

Miturgidae and Mimetidae don't actually have that much in common, but I didn't have enough pics for a whole page of each.

Miturgidae are known as prowling spiders or yellow sac spiders. Cheiracanthium (several species, including C. inclusum and C. mildei) was formerly placed in the Clubionidae family. Like the clubionids, Cheiracanthium are active hunters and hide in silken retreats. Cheiracanthium sp. have been reported to have medically significant bites (not deadly). However, in an online poll, 58 people responded that they had never been bitten, three were bitten with minor symptoms (stinging, small bump), and only one reported that a family member suffered more severe symptoms. I have never been bitten by a Cheiracanthium, even when handling them.

Mimetidae are the pirate spiders. These spiders are unique in that they specialize on other spiders. Some species go into webs of others spiders and subdue the residents; others wait on vegetation for spiders to pass by. The following adult male pirate spider was found in Golden Valley (Minneapolis), Minnesota.
