Syrphid Fly?

Fantastic find!

One of the rarest and poorest known of the Nearctic Syrphidae. Only 4 specimens have been collected since 1930.

This is the first ever live photograph of this species!

If possible do you remember exact coordinates within the park?

Lat: 39* 01' 16" N Long: 77* 14'42" W (approximately) It is upstream from the visitor center around 300-400 feet. The river is lined with Silver Maples that are several hundred years old. And there are wet depressions in the bottom land nearby.

Moved from ID Request.
