Habitat - Callobius nomeus

Habitat - Callobius nomeus
Whitecourt, Alberta, Canada
August 16, 2009
I found several adult males and females under the bark of spruce stumps like these. Some took advantage of holes in the decaying wood, and used them as retreats from which they spread their crinkly webs over the surface of the bark. It was a warm, humid area shaded by tall spruce/boreal forest overhead. In addition to Callobius nomeus, the stumps also contained many other kinds of spiders; among them, Steatoda borealis (Theridiidae); and, many small Linyphiidae, including Drapestisca alteranda which builds an almost invisible sheet web just above and parallel to the surface of the bark.
