Northern Black Widow

How Do You Identify a Northern Black Widow?

  • This cousin of the southern black widow is similar in color and size, but instead of an hourglass, the red on its body shows as splotches or dots.
  • Sometimes the marks will look like an hourglass split in the middle or an incomplete hourglass.
  • Northern widow egg sacs are pear-shaped and smooth. They can contain up to 200 eggs, less than the sacs of their southern counterpart.

Brown Recluse

“There are a lot of myths and misinformation about the brown recluse spider,” Said Benson. “It is exceedingly rare in South Carolina.” The southern house spider, a harmless common spider that shares many of the brown recluse’s physical characteristics, is often confused with its venomous counterpart.

How Do You Identify a Brown Recluse Spider?

  • Brown recluse spiders can be identified by their light brown to yellow color, their relatively small bodies, and their very long legs.
  • The key way to identify them, though, is that brown recluses have six eyes, not eight.
  • Unlike widows, the brown recluse produces egg masses instead of egg sacs. They are flat on the bottom and curved on top. Compared to the hundreds of spiderlings in a widow’s egg sac, the egg mass of a brown recluse contains roughly 40.

This variation of widow first made its appearance in the palmetto state in the late 90s. “It’s actually quite a pretty spider if you look at it,” said Benson.

What Does a Brown Widow Look Like?

  • Brown widow males are 1/3 the size of females, making them the smallest of all widow males in the Lowcountry.
  • A brown widow’s egg sacs are similar in color to those of the southern and northern widows, but they are covered in spikes, which is a stark contrast to the smooth egg sacs of their relatives.

This is the classic shiny shape with the red hourglass on it” said Benson.

How Do You Identify a Southern Black Widow Spider?

  • Female southern black widows exhibit the well-known hourglass shape while males do not, instead having red spots on the top or bottom of their abdomen.
  • Southern widow egg sacs are beige in color and on average slightly smaller in diameter than a dime. These sacs usually contain over 200 eggs and the spiderlings that hatch from them are initially without any of the distinct markings associated with widows.
