Comments & ID Thoughts

My guess is that this species is (Latrodectus hesperus) or the Black Widow Spider. There is a red hour glass shape on the abdomen of this spider. It was found in a cool and damp corner next to my daughter's window. It was found in a very tough and sticky web.

You called this right, I had one lived all summer in a back bathroom. Started as a young juvenile, put her in captivity when she became gravid to remove her eggs. Can’t seem to link to photos, one shows sub adult with dorsal patterns.

Hi Bugman, I just linked my first personal photo (with assistance) to a discussion comment last night. Yay! We didn’t know it was possible, but we attached a sharing link to my photo of a woodlouse through Google Photos and copied that link to the posting. I don’t know how you have been able to link your own photos or videos at all.
