Fine-lined Emerald dragonfly (male)

A Fine-lined Emerald dragonfly (Somatochlora filosa) was spotted during a photowalk at Occoquan Bay National Wildlife Refuge, Prince William County, Virginia USA. Several specimens were spotted along two dirt/gravel roads at the refuge; this is the first one I saw.

This individual is a male, as indicated by his “indented” hind wings and terminal appendages.

Adult Flight Period

According to records for the Commonwealth of Virginia maintained by Dr. Steve Roble, Staff Zoologist at the Virginia Department of Conservation and Recreation, Division of Natural Heritage, the adult flight period for S. filosa is from July 10 to October 15. The species is classified as rare to uncommon. Its habitat is “boggy streams, swamps, and marshes.”

Bear in mind, Dr. Roble’s records are for the entire state, therefore the adult flight period for S. filosa seems to be longer than it is in reality. The adult flight period for a single site is probably shorter. For example, according to records for Northern Virginia maintained by Kevin Munroe, former manager of Huntley Meadows Park, the adult flight period for Fine-lined Emerald is August 23 to October 04.

Rare to Uncommon

A distribution map of official records for Fine-lined Emerald helps to illustrate its classification as a rare to uncommon species of odonate.
