What kind of spider is this? Its kind of big as the newspaper lettering is about 3/4 of an inch..so the spider must be about over an inch long… I live in Sitka Alaska and I found this spider in the house around early December of 2013. I caught it using a glass mason jar. I released it outside after I took this pic of it. Thank you.

We believe this is a Ground Spider in the family Corinnidae, possibly in the genus Castianeira. You can see some similar looking spiders on BugGuide. For your kindness to the lower beasts, we are tagging this posting with the Bug Humanitarian Award.

Any thoughts on this critter?
That one is a female “hacklemesh weaver” in the genus Callobius, family Amaurobiidae. There are only two species recorded from Alaska: C. nomeus and C. pictus. Of those two species, C. pictus is the one that usually has faintly banded legs like this Sitka specimen has. Callobius aren’t your run-of-the-mill house spiders, so this one probably got in accidentally, or was carried in on firewood if the photographer uses a wood stove or fireplace. They are really gorgeous spiders in person, vibrant burgundy or wine-colored!
Wow, thanks Mandy,
I will look for some links.
You’re welcome. =) Here’s also a link to the Callobius section at BugGuide: http://bugguide.net/node/view/18812/bgpage. Not every species is represented there yet, but we have some examples of both the Alaskan species (nomeus & pictus).
Geez, I can’t believe we’re already a month into 2014! Time goes too fast. Happy Chinese New Year to you too!
