Comments & ID Thoughts

I think it might be an Orchard Orb Weaver? It was only small, about 1/2 inch in body length. Seen in web low to ground beside house.

I didn’t give the species because genetic research has found that Except for a region of Florida, the Orchard Orbweavers are all Leucauge venusta in USA. The population boundary lines haven’t been established and the report said that they can’t be differentiated visually. So, for Florida I’ve been saying Leucauge species, and all other states, Leucage venusta. Itsy, what do you think?

I differentiate them by the big red blotches on the sides of the abdomen … they’re partially visible on this one. I only see those blotches on the southern Leucauge, I think it’s a safe bet they’re argyrobapta. This one is from Florida.

Scroll down to “range”, there’s some info and a link to range map here: https://bugguide.net/node/view/1587425

Yes, that’s from the same study. The red blotches do seem to be mostly southern. If someone is using our site for scientific research on Leucauge spp. they’ll still have the photos we’re working from to use. Visual identification of spiders isn’t a genetic guarantee anyhow- as a species or as individuals. I’ve found that mixed species plants are common. It really aggravated me when I was trying to identify them in my neighborhood until one of my newer reference books said, “don’t bother, just go to genus level.” I have a gorgeous little multispecies oak tree in my yard.
