Spider - Amaurobius ferox

Spider - Amaurobius ferox
Litchfield County, Connecticut, USA
April 12, 2006
Size: approx. 1 1/2 in.
We are curious about this spider. We have dogs. Should we be worried?? The markings on the back look almost like a skull.

Check in the guide
under Amaurobiidae - Hacklemesh Weavers and see what you think. Not Harmful to you or your dogs.

Can you please tell me the source of the remark on the Info tab that mentions A. ferox may be found in WA and CO? We got a post on Reddit I suspect is one in Denver. I will ask them to post it to bugguide if they can get a better pic. But I was curious about previous records in CO, since this is otherwise a northeastern species. Thanks.

You are better off posting this question
on the Forums under Arachnological Forum. We doubt anyone will see this question posted here under an image.

john and jane are right. this is also a Coras. the markings are like a skull, or a hockey mask, but they mean or do no harm
