On Thursday I spotted this cool-looking Arrowhead Spider (Verrucosa arenata) , also known as a Triangle Orbweaver, at Occoquan Bay National Wildlife Refuge. This spider is one of the few known orbweavers that sits facing upwards in its web—all other species face downward.
Its distinctive triangle-shaped abdomen makes this species pretty easy to identify. If you look closely at the image, I think that you can see a couple of the spider’s large round eyes shining brightly in between several of the legs in the upper left portion of the spider’s body.
