Hi,
Great site!
Have a question about black widows. When we lived in the New Orleans area, we saw several spiders that were black and shaped just like a black widow, but had red markings on the top side of the abdomen.
I have not been able to find anything online that resembles them , and thought you might be able to help.
Thanks,
Mary P

Hi Mary,
First, the red hourglass is on the under side of the abdomen. There is a spider known as the False Widow, Steatoda grossa. Both the true and false widows belong to the Comb Footed Spider Family Theridiidae. The False Widow is a beneficial spider, reported to prey on its more poisonous relative. It also eats Sow Bugs. It is a hardier spider than the true Black Widow. We find them in our yard all the time, and will take a photo the next time.
