Black Widow

  • Food: Insects.
  • Web Irregular mesh with a funnel-shaped retreat, built in sheltered spots.
  • Life Cycle Female rarely leaves web, stays close to egg mass, biting defensively if disturbed. Pear-shaped egg sac, 3/8-1/2″ (8-12 mm) wide, is pale brown. Female stores sperm, producing more egg sacs without mating. Spiderlings disperse soon after hatching. Some females live more than 3 years
  • Habitat Among fallen branches and under objects of many kinds, including furniture, outhouse seats, and trash.
  • Range Massachusetts to Florida, west to California, Texas, Oklahoma, and Kansas; most common in the South.
  • Despite its reputation, this spider often attempts to escape rather than bite, unless it is guarding an egg mass. Males do not bite. After mating, the female often eats the male, earning the name “widow.”
