Roach - Periplaneta americana

Roach - Periplaneta americana
McMinnville, Yamhill County, Oregon, USA
February 23, 2011
Size: 3/4 inch
This (Oriental) beetle is approx 3/4" long. The picture was lightened up a bit in hopes facial features would show up more.
It is soft bodied with no wings. Perhaps an instar of Blatta orientalis. It was found in a public restroom.
Thanks you for any help towards a positive ID,

Lightened roach
The wing-like appendages on left side of this cockroach appear odd. I can't trace the lines of the thoracic segments very well, and I'm not sure if it is from the altered coloration. Could you upload a photograph with the normal color?

Sorry I did not get your email to upload another specimen
I have posted another specimen,
Thanks Jake.

Cockroach nymph
Thanks for adding the second image. I think that in the first image, the left wingbud on the mesonotum was tucked under the wingbud of the metanotum. In most adults that have vestigial wings, they are on the mesonotum, with the appendages of the metanotum absent or much smaller in size. Thus I believe that you have a cockroach nymph rather than an adult. It certainly could be an Oriental cockroach, but I am not able to distinguish this species from others- such as an American cockroach. There should be reliable characters to identify these nymphs, but if any have been published, I do not know of them.
