Wolf Creek, Josephine County, Oregon, USA

Size: over an inch
i found this at a friends house about 2 miles from mine walking down the sidewalk, near their garage. i was shocked, it looks like a giant cockroach? i have never seen anything like this in 57 years here in Wolf Creek!


Yes indeed- this cockroach is very different from members of other cockroach groups. For instance, they have very similar endosymbionts to those found in dampwood termites- beautiful protozoa that spin and swirl under the microscope (and presumably within their digestive tracts as well). It is odd that this one was out for a walk down the side walk. In some cockroaches, being parasitized by a horse hair worm causes them to search for water, so that the worm can finish its strange life cycle. If you still have this cockroach, give him some water and see if something pops out!

Moved from ID Request.

nice roach, weird behaviour
not only these have same kind of gut microflora/fauna as termites, but they have been found to be more closely related to the termites than to the rest of cockroaches -- which, if i'm not mistaken, is the main reason why the old Blattaria couldn't be sustained as a monophyletic group separate from the termites.
during a collecting trip to the area right across the Pacific from your place (~35mi n of Vladivostok) i observed, on several occasions, charming family groups of a similar wood-eating roach, Cryptocercus relictus. Like termites, they avoid going outside -- but, unlike termites, don't have alates, and thus are seldom seen.
your sidewalk encounter is sure an unusual occurrence -- but Dr Carlson's suggestion makes total sense. Parasites have clever techniques to make hosts behave in ways maximizing the parasite's spreading potential.

its been awhile but..
i wanted to tell you that a week after i found it it just died..i dumped itin a flower pot outside and the next day i found a living one crawling around the base of the pot..i checked and the dead one was still in the pot..this was about two miles from my friends house where i found the first one..very strange huh?

you bet :]
Edna, by any means, please take more pics of these for the Guide if you see any again, okay? i don't expect them to be all that uncommon, they just lead their quiet lives deep inside red-rotten trunks. must be docile and cooperative as photo models, too.

well as of now
i am living in Wyoming for a couple years but i surely will when i get back keep an eye out.

so normally where do they live and what do they eat?
rotten wood ?

from experience, in/under fallen trunks on advanced stages of decay

okay ill do that!
it just so happeneds that i do have him..he just walked out of a rockwall and down the walk at me like he owned it..i thought that possibly he had been bought here in a delivery from usp or something..i just had no idea we had anything like this here.

It looks a bit like this one, which was indeed found in Oregon:

I'm sure John Carlson will be able to say for sure.

well i have to say i learnsomethingnew every day!

definitely looks like a Cockroach
Sure looks a lot like a Madagascan hissing cockroach, but I don't think that's it.
