I photographed this pair two days ago, in woodlands, alongside a very small stream. Location: West Virginia, USA.

My size estimates made by measuring the images are 6.6 mm for the female and 4.1 mm for the male.

ID help appreciated!

Good call, Proctoss! Before you replied, I sent the page link to Brian Brown, the expert on Nearctic Phorids. His reply came back, Gymnophora luteiventris.

Thank-you Tony, Nikita, Proctoss, and Brian Brown!
