He landed on gravel road/path.

Efferia aestuans (Linnaeus 1763)?

Moved from Efferia.

Terminus is correct
for aestuans male. I am still impressed that this species from different parts of the country has 2 to 3 to 3 1/2 silvered segments in the male. Not consistent. Though the other features are all stable.

Thanks Herschel.
