Albino black widow?

Asked February 9, 2018, 8:43 AM EST

I found this one with egg sacs user a wheel barrel. It reached for the eggs sacs to save them when it knew I was there. What is it?

Dear Client,

I have heard about these female black widow look-alikes, but this is the first time I have seen one. Your spider is actually known as the female brown widow, Latrodectus geometricus. It is common to California and the Southernmost US States.

According to BugGuide, "The brown widow is highly variable in color. It may be almost white to almost black." The darker the spider's color, the more difficult it is to distinguish this spider from the black widow. The banded legs is another feature that helps us distinguish between the brown and the closely related black widow female spider. Incidentally, the egg masses are also typical of the spiders in this Latrodectus genus.

"Be very careful when working around areas where widow spiders may be established. Take proper precautions-wear gloves and pay attention to where you are working. The reaction to a widow bite can be painful, and the victim should go to the doctor immediately for treatment." -BugGuide

"However, brown widow bites are usually not very dangerous; usually much less dangerous than those of L. mactans, the black widow." Wikipedia- Los Angeles Times. Retrieved 28 September 2012.
