Pisauridae (Nursery-web Spiders)

Dolomedes tritonDolomedes tritonDolomedes triton (Six-dotted Dolomedes) (Lower Vine Brook, 8/30/08 1pm #1, 9/1/08 11am #2&3, Whipple Hill, 8/24/09 1pm #4-6) I scared the spider in the second picture and it dove underwater, giving me a nice photo! The female in the 4th & 5th pictures was guarding her nursery web, 6th picture. Her abdomen was greatly reduced from the energy expended in creating the egg sac and eggs, as well as the presumably more limited feeding during her watch over her young.

There were two of them hunting on our Burlington patio at about midnight. They both measured about 3.5" long, with the bodies about 1" long. The first photo has a ruler next to it. It looks fake, but it isn't. I had to lighten that portion of the photo to get it to show up.

Tetragnatha sp. (Willard's Woods, 6/2/07 9am)

(Lower Vine Brook, 6/17/12 11am) Possibly same as above. The jaws of this one look smaller, but it is hard to tell from these pictures.

(Lower Vine Brook, 6/29/13 5pm) This poor spider had a nasty case of mites.

Tetragnatha sp. (Whipple Hill, 8/24/09 1pm)

Meta ovalis

(Lower Vine Brook, 6/23/2019 1pm) It certainly looks like a male tetragnathidae, but I can't find one that looks similar.
