Contrast the appearance of a mature male versus immature males of the same species: http://www.projectnoah.org/spottings/22816079 Notice the scratch marks on the abdomen of this mature male dragonfly. "Males that have mated often have marks on their abdomen where the female legs have scratched them. This is especially obvious in species in which males develop pruinosity, as the pruinosity on the midabdomen is scratched off, and the signs are visible at some distance."
