Good post. When it was still alive it had a strong resemblance to that photo with its legs. It crunched up after the bug spray.
I was leary of it since moving south many years ago I saw my fair share of black widows. One time under the cover of our boat, I reached under to take it off was my first experience. My hand entered this finely knit web that like sticky paper stuck to my hand, pulled my hand out and looked and there was the spider with arrow glass.
2 years ago moved into a brand new home and I swear, I think I had three of them in each corner of the garage minus one corner.
So anyway, now leery of them I saw this guy and who knows if anymore under a pallet from a delivery of bagged mulch in my driveway. I had to slip my hand between the boards to move it now that I got the much off it. After seeing they I sprayed the bottom to be safe before picking it up.
Anyway, I guess it also could be that corncob spider but whatever it was, it was close enough in those photos not to take chances.
The part that sort of makes me think it wasnt corncob was it didnt have "diamond" pattern. Looked more like your photo.
Anyway, thanks to every one for their thoughts. .... AND ... here we are a year or two later I see some spiders in the corners. I'll take a closer look, post photos if I see the familiar close knit silky nest of the black or brown widow.
