Point of the Rocks and Lander's Boat Launch on the Potomac River April 29, 2024

[odona...@comcast.net]

I spent several hours yesterday searching the banks of the Potomac River for cast skins of Ophiogomphus susbecha without success.  In fact, I only saw 6 dragonflies  (5 species) and no damselflies.  Considering the record-breaking temperatures (approaching 90 degrees) this was disappointing.  The single Spine-crowned Clubtail taking its first flight, an S1 species, was really the only highlight.
