Pisauridae (Nursery-web Spiders)

Dolomedes 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.

females spiderlings in nursery web Pisaurina mira (Burlington, 6/10/00 1am #1-4, Lexington, 6/23/02 11pm #5-7, Willard's Woods, 8/21/12 6pm #8, Lexington, 5/28/04 12am #9, Willard's Woods, 8/12/11 2pm #10, Parker Meadow, 8/20/12 11am #11-13) The first 5 pictures are photographs of the biggest spider I've ever seen in the wild in North America. 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.

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.

Tmarus angulatus (Willard's Woods, 5/20/09 10am) Unfortunately, these came out quite blurry. The tubercle is not noticeable on this specimen, but everything else looks like I've identified it correctly.
