Hacklemesh Weavers

Hacklemesh Weavers are a family of spiders (Amaurobiidae) known to build irregular looking webs in bark and woodpiles.

They share many similarities with the Funnel Web spiders, although the funnel web spiders mostly build their webs in grass. Both can live through the winter, and therefore they are often found in households during the cold weather.

Physically, they tend to have a two-toned body with a shiny looking cephalothorax and fuzzy abdomen with a pattern. The red cephalothorax of the spider in the top picture is a good field identification clue for the largest members in the Callobius genus.
