Comments & ID Thoughts

Based on other photos I've seen online, both here and on other sites, I'm thinking it's a Giant House Spider. Having said that, I swear I've seen the same spider pic used as a classification for the GHS as well as a Hobo Spider so maybe I'm wrong.

Hi, welcome to Spider ID. 🙂 I agree this looks like a Giant House Spider (either Eratigena duellica or saeva), the Hobo Spider (Eratigena agrestis) is in the same genus so it’s possible it just looks similar to you or that someone else put the wrong ID on one (happens all the time) because they do look similar.

Seems E. saeva is being phased out by AAS, E,duellica in Wa. and Or., E. atrica in the great lakes region and Canada. Hard to stay on top of all the changes.

Hi. If this helps, the first obvious difference is with size, the Giant getting easily double the size, and the leggy males I have seen getting to a 4 inch legspan. A smaller giant next to a large hobo, nearly identical. Because I freely handle these, I can pick them up and look at plumous hairs on the legs and examine the mouth parts for denticles with magnification and tell them apart. Giant house spiders displace the hobos so you don’t typically find both in a small region. A nice female hobo I caught near Spokane Wa. https://www.flickr.com/photos/32083154@N02/9465466366/in/dateposted/ Body est.… Read more »
