@Arjuna,
I recognize these spiders but I don't just know they are widows. The neighbor telling me they have them corroborates my fear. I didn't have time to see a violin, etc, on the underside of the spider working the sink. But I recognize it, from back in LA. Indeed, some of my black widow fear is from my family.
Are there close mimics of black widows?
I might have posted on this. I was buying a bottle of something at walgreen's and for some reason the checker started talking about a spider bite... thus I got that she sat on a log locally and was bitten by a brown recluse. Well, not immediately locally. And was hospitalized and so on.
Tell me more about not-webs.
Back in Venice, I associate nests, but didn't run into these webs.
With any luck, I'm wrong..
