Brown Widow

Latrodectus geometricus


Brown spider with orange hourglass on underside of bulbous abdomen seen at night. The juvenile brown widow can be seen at


Backyard at night. They hide during the day.

No species ID suggestions


:) I hope they're right about the venom. I didn't notice the take over but when I started last year and looked for a Black Widow, I could only find the Brown Widows.

I did see that one and added to my collection for reference in the favourite department.
Surprisingly, I have not seen brown widows here. Black are around and very strong. I think it would be a battle for the brown to take over!
I read in the article that the brown are less venomous.
Now that I know of the brown widows existence , I will keep my eyes open.

Nice Emma. Here's what a juvenile Brown Widow looks like for a brief time

I just included an article about brown widow in the comment section of this spotting. and then I saw your spotting!Good to see what one looks like!

It's really true! I rarely ever see Black Widows at night now. These are everywhere. Their egg sacs are tan with bumps all over the outside. Oddly enough I don't have a spotting of one. There's one in my future I think :)

I hear there has been an increase in the brown widow in San Diego County. I've not seen any along the coast. Glad to see what they look like. :)
