female egg sac Argiope aurantia (Black & yellow argiope) (Willard's Woods 9/22/02 1pm, 8/30/06 6pm, Parker Meadow, 8/25/12 12pm, Lower Vine Brook, 8/28/12 6pm) The last 4 photos are of a spider my son & I captured and kept for a class project. She laid the egg sac shown here, as well as a second, smaller egg sac, before dying in the middle of September. We fed her grasshoppers, katydids, and beetles, such as the Locust borer in the photos, and at her biggest she was substantially fatter than the spider in the 2nd photo. After laying the egg scan shown here, she lost roughly half her mass and appeared unable to spin a web. We managed to get a grasshopper caught in the silk surrounding her egg sac, which the spider then ate. After that, she started spinning webs again and we continued to feed her (all 4 photos are from this time period). She did not fatten up too much before laying a second egg sac which again cost her about half her mass. This appeared to be too much for her and she died within two or three days.

Araneus bicentenarius

Araneus bivittatus

Araneus cavaticus (Barn Spider) (Lexington, 9/1/01 12pm, Lower Vine Brook, 9/22/09 12pm) The first spider shown (2 pictures) made several webs in my garden before constructing its masterpiece -- a nice medium-sized web with supports linking the house and the detatched garage, a span of more than 10 feet!

Neoscona crucifera

Neoscona domiciliorum

Neoscona pratensis

Larinioides cornutus

Larinioides patagiatus? (Arlington Great Meadows, 4/24/10 11am) Too windy to get a decent photo. I'm not very confident of this identification.

Eustala anastera or cepina (Lower Vine Brook, 8/12/12 1pm) Perhaps immature? It was quite small.

Eustala anastera (Willard's Woods, 5/23/07 4pm) This spider had built a very nice web, but it was so windy that I ended up bumping into it. I had to photograph the spider on a stick to keep it still enough, and even then the photo ended up a bit blurry.

This is an enormous family with hundreds of species. I have only had the energy to include the species from the 2 genus I have photographed.

female male mating Neriene radiata (Filmy Dome Spider) (Willard's Woods, 6/2/07 9am (2), last female, male, & first mating Lower Vine Brook, 8/19/17 12pm, 6/5/2020 5pm (3)) Unfortunately, I don't have a good picture of the web which would help in identification. This one looks very similar to the spider below, but the colors are definitely different. The male inflates his pedipalp during mating. The video here shows it inflated for a prolonged period. The spider I photographed kept it inflated for no more than a few seconds and unfortunately I couldn't get a sharp photo.

Neriene clathrata

Neriene montana

Frontinella communis (F. pyramitela) (Bowl and Doily Spider) (Willard's Woods, 7/10/05 5pm, 5/23/07 4pm, Lower Vine Brook, 7/14/2019 4pm)

male female Rabidosa rabida (Lycosa rabida) (Rabid wolf spider) (Willard's Woods, 7/21/02 11am, 9/24/11 1pm)

Rabidosa punctulata

Pardosa sp. (Willard's Woods, 5/27/02 2:30pm, Lower Vine Brook, 5/30/09 11am) These spiders are extremely numerous. I'd estimate perhaps 1 per square foot in the damp fields.

Pardosa sp. (Willard's Woods, 5/13/07 11am) This spider inhabits the same territory as the one above. It doesn't seem as numerous. It might just be a color variant of the spider above.
