German Cockraoch or ? - Ischnoptera bilunata

German Cockraoch or ? - Ischnoptera bilunata
Lakeland, Polk County, Florida, USA
July 10, 2010
Size: 3mm - 3.5 mm
I'm not sure if this is the German cockroach or another type of roach..
I keep finding them outside on the back patio, My house was just built this year (march 2010) so I'm hoping they aren't German cockroaches.

Moved from Asian Cockroach.

Based on the following:
Venter of abdomen appears to be dark in 3rd pic
Tegmina appear abnormally dark for B. a*sahinai
Base of pronotum with dark markings

The presence of these outside of the house indicates that they are Asian cockroaches (Blatella asahinai) rather than German cockroaches(B. germanica). While German cockroaches will wander outside now and then, they don’t typically survive for long, and you wouldn’t see so many of them on your porch. This image also is a good view of the face, which is important for separating it from the Field cockroach (B. vaga). That species is not yet in Florida, but it probably will be eventually. Just as the Asian cockroach is moving steadily westward from Florida, the Field cockroach is moving from the west coast eastward.

Moved from ID Request.

It it was
out and about on vegetation during the day, it's an Asian cockroach.

mm, not cm?

I don't know...
what kind this is for a sure ID. The markings seem to be able to fit the German but can also be the Asian. While you wait for an expert ID (if you haven't) visit this site.

Maybe reading about behavior and seeing some size comparisons will help you decide the type of roach you are seeing.
