Off-season homework pays dividends

The ode-hunting off-season is used by the author for experimenting with new photography gear and techniques, studio photography (mostly odonate exuviae), and researching/exploring sites for finding new species of dragonflies and damselflies, especially rare to uncommon species.

During Winter 2017-2018, Google Earth/Maps was used to virtually explore potential sites for Sable Clubtail dragonfly (Stenogomphurus rogersi). A location where Sable Clubtail had been spotted by Kevin Munroe, former manager of Huntley Meadows Park, was rejected as practically inaccessible.

I recalled seeing Sable Clubtail on a species list for one of several sites surveyed regularly by a group of volunteers coordinated by Jim Waggener, in association with the Audubon Society. I contacted Jim and asked for information regarding sightings of S. rogersi by the survey group. Jim sent an e-mail to all members of the group; Bob Blakney kindly responded by sending a photograph and guidance for finding the location where his photo was taken on 08 June 2012.

As it turns out, only one Sable Clubtail was seen by the survey group in 2012 and that was the last sighting of the species for the next six years. I speculate the gap in sightings might be explained by the fact that scheduled dates for site surveys by Jim Waggener’s group didn’t coincide with the limited adult flight period for Sable.

I scouted the site for the first time on 01 December 2017. Fred Siskind kindly provided guidance that helped to focus the search area. I started actively hunting for Sable Clubtails beginning in mid-May 2018. 04 June 2018 was my last fruitless search. The off-season homework paid dividends for the first time on 08 June 2018.

Eureka!

Several Sable Clubtail dragonflies were spotted perched alongside a small forest stream located in Fairfax County, Virginia USA.
