Eastern Pondhawk dragonflies (females)

The following photographs show a couple of female Eastern Pondhawk dragonflies (Erythemis simplicicollis) spotted in a meadow located at least 100 yards from the central wetland area at Huntley Meadows Park.

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.
