Eastern Pondhawk dragonfly (female)

Erythemis simplicicollis


An Eastern Pondhawk dragonfly spotted during an Audubon Naturalist Society field trip to the North Tract of the Patuxent Research Refuge. This individual is a female, as indicated by its green coloration and the subgenital plate, a black "shark fin" located beneath segment eight of the abdomen. "Underneath segment 8 there is either an ovipositor or a subgenital plate, depending upon the species [of dragonfly]. Both structures are for laying eggs and extend over segment 9 and possibly beyond." Source Credit: _Dragonflies of the North Woods_ by Kurt Mead.
