Summertime Nature in New Jersey: Sourland Mountain Preserve.
Back at the Sourland Mountain Preserve. This is the same Dragonfly like insect that was in my 19-August-2011 post. It is as large as a Dragonfly, but is not one since it only has one set of wings. When they are not mating, they are aggressive carnivores, catching and eating other insects. [Finally identified as a Robber-Fly. Thanks to Hans for sending a link.]
