"Both the cockroach and the bird would get along very well without us, although the cockroach would miss us most." - Joseph Wood Krutch  A female Oriental cockroach, Blatta orientalis, native to Asia. They're a commonly seen introduced species throughout much of the world (including Maryland). Males have noticeably longer wings.   Try viewing the large version or the original. The smaller version lacks detail. This photo was also featured here: www.maxklein.es/2007/06/08/ortopteros/
