Spider?
Hi Bugman
I discovered this spider on the steps at work in Kill Devil Hills N.C. two days before Christmas at around midnight. I thought she was absolutely gorgeous so I took a couple pictures and returned her to the wild. I believe from your site that it is a female Trapdoor spider. I just love the blue abdomen. Can you confirm my supposition and any further information would be appreciated!

We agree that this is a Trapdoor Spider. It is in the genus Ummidia. We are not convinced it is a female. Females rarely leave their burrow and it is the males that wander in search of a mate. The legs on your specimen seem short (could be camera angle) like those of a female, but the pedipalps are rather large, indicating a male spider. Perhaps someone with more knowlege will write in to clarify.
