This odonate flew up almost from under my feet and landed down in the grass a few feet further on. Every year at about this time I seem to scare up one or two of these dragonflies as I walk along trails by the old field. These are one of the few odonates to be found flying at dusk and later. In fact, in 2009, when Diane and I were mothing at the FWG, one stayed on the sheet the entire time we were there (until midnight).
