Amaurobiidae

 

Callobius bennetti hides along the forest floor and is not usually seen even though they are widespread. Females are 5 to 12 mm, males are 5 to 9 mm, and legspans are 12 to 18 mm. Egg sacs are produced during the late summer and fall and immatures overwinter.

Callobius bennetti - Bennett’s hackledmesh weaver

Amaurobiidae are hackledmesh (or hacklemesh) weavers. The common family name comes from the distinct “hackled” web type. These spiders make webs among logs, bark, and rocks. The webs may resemble those of Agelenidae.
