Eastern Pondhawk dragonflies (females)

Eastern Pondhawk dragonfly (Erythemis simplicicollis) is another species of dragonfly with prominent pseudopupils, as shown by several specimens spotted during a photowalk at Huntley Meadows Park on 22 July 2014.

These individuals are females, as indicated by their green coloration and white terminal appendages. See Eastern Pondhawk dragonflies, a photo-illustrated guide to the identification of male- and female terminal appendages.

Look closely at the following photo. Notice 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.

Remember that “Segment 8 and 9″ refers to abdominal segments eight and nine (of 10), numbered from front to back. Digital Dragonflies features a side view of a female Eastern Pondhawk in which the subgenital plate is shown clearly.
