Linyphiidae Helophora sp.

Order: Araneae

Family: Linyphiidae (Sheet Web Spiders)

Subfamily: Linyphiinae

Genus: Helophora

This spider has eight eyes, but the posterior and anterior lateral eyes are so close together that they may be mistaken for two large eyes. The body is white and pale brown with a ring of darker spots. The abdomen has a distinctive arrow shaped pattern on the back (see picture). The legs are very long and thin, and have many relatively long spines. The body of the male is quite thin, the females are broader. The female is 3.5-4.0 mm and the male is 3.0-3.5 mm.

Bogs and wet meadows, sometimes deciduous and coniferous leaf litter.

Sheetweb spiders spin horizontal sheets of webbing, and hang underneath it. When prey walks across the sheet, the spider bites throught the sheet to catch the prey. They have special structures on their fangs that they can rub together to make sounds used in mating, and possibly in territorial behavior.
