The glossy, black-bodied female widows have distinctive red spots on the underside of their abdomens. In L. mactans this spot often is shaped like an hourglass; in L. variolus it is not. Faint red or white spots may also appear on top of the abdomen, as they do in males. Only the sedentary female black widow is capable of inflicting a potentially dangerous bite; the wandering and seldom-seen male is harmless.
