A Domestic Scene. Or, a scene of domestic violence! I picked up this piece of wood in our wood shed. The female had stayed with the young and it appears that there is an “expired”, dismembered male in the frame as well. Truly a jungle out there! Callobius severus,Canada,Fall,Geotagged

Appearance

Cephalothorax and legs are reddish to dark brown and the abdomen is dark to light grey with fine hairs, often appearing with large, bilaterally mirrored paler spots. Males feature large, extended palps with prominent projections.
A Closeup of Callobius severus I am thinking that this fellow is a female because of the shape of the abdomen and the small palps. Without the use of the flash this photo would not have happened. Their bite is supposedly painful but this spider was more interested in heading for the dark underside of the piece of wood in our woodshed. Callobius severus,Canada,Geotagged,Spring

Habitat

It is a nesting woodland species commonly seen in the Pacific Northwest, and one of the most commonly found and widespread spiders in populated areas of Washington state.

It can often be found in households and other man-made structures with thin funnel webs, so long as the niche has not yet been filled by another organism. The species poses no threat to humans or pets, though like other ''Callobius'' species, the bite is painful.
