Color: Dark or black in color with a red or orange hourglass on the underside or bottom of the abdomen.
The Southern Black Widow is glossy black with a red hourglass marking on the underside of its abdomen. The female is much larger and more distinctly marked than the male. It makes a strong, sticky irregular web in protected areas where prey is likely to wander in and be trapped.
Foundations, vents, shrubs, outside seats, trash and wood piles at ground level are common habitats. Their poisonous venom can cause concern for small children and older or sickly persons. Medical attention should be sought if bitten.
