Spiders of Oklahoma: Black Widow

August 12, 2013

The female black widow spider (Figure 3) is slightly larger than the brown recluse and is glossy black in color. It is globular in shape and never hairy. It has eight eyes arranged in two rows. The overall length of the female (legs extended) is about 1 1/2 inches and the male is much smaller, about 1 inch long. The male usually has three light streaks on his abdomen but is recognizable by knob-like appendages on the front of the head. The female has slim, glossy black legs, but the best recognition mark is a reddish hourglass-shaped spot on the underside of her globular abdomen.
