Calls regarding solpugids usually begin some time in the spring and continue pretty much through the summer. It has features that make it look like a cross between a scorpion and a spider. There are reportedly more than 120 described species, with 26 of them being found in Texas. Like most arthropods, it takes an expert to tell the species apart. Their color is usually tan to gray-brown and they are quite hairy.
Females are indistinguishable from males.
Adding legs and pedipalps, they may span three inches or more. On the underside of each of the last pair of legs solpugids have an interesting set of five T-shaped racquet organs that are also sensory in function. The general body shape and color resemble a scorpion except that it does not have pincers or a tail. Despite their appearance, solpugids are not dangerous to humans. They are nocturnal creatures, usually hiding during the day under stones, wood, etc., and coming out at twilight or later to search for insect prey.
