striped jumping spider - Habronattus calcaratus -

Sudbury, Middlesex County, Massachusetts, USA
April 8, 2005
Size: 1/4"

I went to the newly opened Assabet River NWR and found loads of these distinctive little jumping spiders. On the edge of one sandy/grass field there seemed to be one of these on top of every little 1" rock. Could this have been displaying for a mate?

another calcaratus?

Again, same comments. I wonder if this could be calcaratus maddisoni rather than viridipes.

green on front leg. Moved images. If you disagree, let me know and I will move back to genus.

Habronatus?

Here are a couple of images that have some similarity to yours. It might give you a genus to pursue. cognatus, and cuspidatus. Might be interesting to see what members of the genus are in your area. Also, LINK is usually reserved for multiple pictures of the same animal. If these shots are of the same species, but of different animals, you should unlink them. Link those images that are of the same individual.

Habronatus

Thanks. I couldn't find an exact match, but the genus Habronatus is right. The genus identifier is the third leg is much longer than the fourth. The third leg in these is much longer, with a high arch in it. The males of Habronatus are brightly patterened, and the females are generally grayish. Here's a good site with lots of pictures.
