Micrathena gracilis
(Spined Micrathena)

Comments & ID Thoughts

I have never seen a spider like this before. This summer I have seen multiple. Does anyone know what they are? It’s small, penny sized, and black and looks bat-like with the points. It crawls with its abdomen up in the air like it’s carrying a pyramid on its back.
