[1] The bodies of these spiders are rather compressed in the vertical direction, which allows them to hide themselves under the loosened bark of trees and in other tight places.

They have a prominent chevron-like pattern on their abdomens which may make them more difficult to distinguish on mottled surfaces.

Eggs are laid and hatch during the summer, and adults and other stages overwinter in their individual silken shelters.

Although the shelters are built separately and keep the spiders out of direct contact with each other, Kaston reports that as many as fifty of them may crowd their shelters for hibernation together so tightly that they form a continuous blanket under the loose bark of a standing tree.

The distribution of this species ranges from the Eastern States and adjacent Canada, to Texas and Wisconsin.
