Scorpions

Adults average about 2-3/8 inches (60 mm) in length, with the tail being longer in the males than in the females. Body color of adults varies from yellowish to tan, marked with two broad, blackish stripes on the upper surface of the abdomen. Populations in the Big Bend area may be only faintly marked or completely pale. There is a dark triangular mark on the front (anterior) portion of the head region (carapace) in the area over the (median and lateral) eyes. Younger specimens may be overall lighter in color, and basis of the pedipalps and the last segment of the body (postabdomen) is dark brown to black. The key recognition characters for this species are the slender pedipalps and the long slender tail.

Scorpions use the pincers to capture and hold prey. This species occurs under rocks, under boards, and in debris. It can be found indoors or outdoors in a wide variety of habitats (pine forests in East Texas, rocky slopes, grasslands, juniper breaks in other parts of the state).

Most common and widespread scorpion in Texas; stings are painful and produce local swelling and itching that may persist for several days. Reaction to the bite may vary based on sensitivity of the individual. Non-lethal stings may be mild to strong and produce edema (swelling), discoloration, numbness, and pain which may last for several minutes to several days. Deaths attributed to this species are not well substantiated. There are no scorpions in Texas that are considered lethal to man.
