Comments & ID Thoughts

Uloborus glomosus? It is the thing that looks like a bud at the end of the twig. Note the hairs on the legs, distally. It kept posing as a bud. I've seen many of these in the woods here. They are small and escape easily and are difficult to photograph.

One species in Uloboridae? There’s ~15 spp. in 7 genera in North America. Might only be one in NH, that I’d need to check.


OK, I see it might be Hyptiotes. That looks better, I need to compare it when I’m not on a phone. My mind went straight to Uloborus glomosus which is more twig-like.


Head and legs look like Micrathena, not sure from this though.


I didn’t comment on most of them to save time but I went through and labeled most of your images.


OK, not a lot of detail but close enough that I filed it. Looks like you were right with Uloboridae, just a different genus. Should just be the one species in your area. Hyptiotes cavatus. 🙂
