Description

Brown widows can vary in color intensity and pattern ranging from light tan to dark brown. There may be a red broken stripe or a series of white spots along the top of the abdomen with parallel rows of black spots on either side of the stripe. The brown color can be very dark, almost black. There is an orange hour glass mark on the underside of the abdomen in both females and males. The cephalothorax (head) is usually dark brown. Legs are usually tan and black banded.

Identification
The brown widow is highly variable in color. It may be almost white to almost black. Typically, it is a light to medium brown, with an orange-to-yellow hourglass marking on the underside of the abdomen; the coloration of the hourglass often is a good indication of this species. The leg segments are banded, with one half of each segment lighter in color than the other half. The back often has a row of white spots (rarely orange or light blue), and there are a few white stripes on each side. Darker individuals lack these markings and are difficult to distinguish from black widows.
