Description Windscorpions are members of the eremobatid windscorpion family (family Eremobatidae). Most North American windscorpions belong to this family of medium-sized arachnids, 5/8-1 3/4" (15-45 mm) long. They differ from the only other North American family, Ammotrechnidae, in having a straight front of the head and 1 or 2 claws on the first pair of legs, rather than a rounded or pointed head and no claws. Adults usually live only a few months. All are found in the West, particularly in the Southwest.
