Outdoor Oriental cockroach - Blatta orientalis
Philadelphia County, Pennsylvania, USA
August 4, 2009
Size: ~30 mm
Astonishingly, this is a BugGuide first for Pennsylvania. Blatta orientalis is very common, but there are only 30 images on the Guide - I've seen that many at once under a Dumpster!

Looks like this is probably Blatta orientalis after all, can any roach experts confirm?

Is this one of the wood cockroaches, P_arcoblatta sp.?
After moving to the city, I developed a pretty strong antipathy to cockroaches, but to my surprise this outdoor roach didn't bother me at all. As they say in real estate, "Location, location, location."
