Being the local “Bug Guy” I was recently asked about a spider that looked “almost exactly like a black widow,” but lacked the distinctive red hourglass on the underside of its abdomen. This is a spider with which I am very familiar. They were nearly everywhere where I grew up in Pacifica, California. I hadn't seen any hereabouts but I was fairly confident what was being described was a female “false black widow” or
Steatoda grossa. Although in the same family as the notorious mate-killer, this spider is much less dangerous and is usually timid. Neither are they the typical jet black of the widows, but usually a dark maroon.

I was discouraged at the time because I didn't have any photos of the species and a tour of my yard didn't turn any up either. That was until two days ago I looked over the door to my bathroom and there she was. I collected her, took pictures and let her go. This is a nearly harmless species which is beneficial in that it destroys other spiders and pest insects.

California Spreadwing. I love shadow pictures.
My most recent amble along the Van Duzen turned up several California spreadwing damselflies (
Archilestes californica) and a single variegated meadowhawk dragonfly (
Sympetrum corruptum) who was too agitated to get a shot of perched, but who did hover just long enough to get a shot of in the air.

A single Mylitta crescent (
Phyciodes mylitta) put in an appearance. The larvae of this cheerful little orange and black butterfly feed mainly on thistles and their relatives.
