This one was surprisingly straightforward to identify. The lack of a sclerite at the base of the lateral hump narrows the field quite a bit, and the other options followed fairly obvious characteristics to Clostoeca, which only has one species, Clostoeca disjuncta.

Jason, I work for a not-for-profit company, Professor Garfield, which, in conjunction with the state of Indiana and Ball State University, is putting together an educational web-site for migrant children. We are building science modules. One of our needs for our life cycle modules are photo/video images of dragonfly nymphs, eggs, and dragonflies laying eggs. Would you give permission for us to use your video/photo of a dragonfly nymph? Do you have and could we use any other dragonfly life stage images you have?
