The females have the hour glass shapes on their backs. Also, the females are usually quite a bit larger than the males. You're more likely to see a female because their survival rate is higher. Males also aren't as poisonous.

The female black widow spider is larger than the male, and therefore carries more venom.
They mate with female Black Widows, and since the male knows that mating with the Black Widow will ultimately lead to his death by cannibalism, the black widow technically commits suicide just for the Black Widow spider to live and pass on.

The black widow is the only spider in Georgia known to resemble a black widow but be entirely black. If you spot a black spider in Georgia that looks similar to a black widow but is completely black, it is likely a black widow spider. While rare, variations in color can occur within the species.

AnswerIf it is predominately black and has the red hourglass on the abdomen, it is a black widow. It is my understanding that the stripes denote either a male or a younger female.

The male is considerably smaller than the female and has different markings on it's abdomen. Marjorie Moody claims: "I have never heard of an adult male black widow being implicated in poisonous bites. I assume that they are relatively safe."
