Thanks to Student Doctor Inna, I now have the female counterpart of the European Mantis. I thought I would post the photos in comparison, as well as provide more information about this species. The female is more drab colored, a golden brown/olive green almost - most likely for better camouflage. Also, she is about twice the size of the male mantis. I waited a day before preparing her for pinning, and the jar became coated with a slick pungent liquid - possibly pheromones. This is the first non-Lepidopteran I am pinning using the spreading board, so hopefully she will come out looking fantastic!
M. religiosa originated in southern Europe, hence the common name. It was accidentally introduced to North America on nursery stock. They are now found across the United States, and are most easily identified by a dark spot on the inner side of their fore coxae. The female's spot is entirely black, but the male's has a white spot with a black outline. M. religiosa is the state insect of Connecticut. It is also good to note that when in Europe, it is simply called a praying mantis, in the same way that Brazil nuts in Brazil are simply called nuts.
