Shore Fly - Brachydeutera longipes

Brachydeutera longipes Hendel

Moved from Brachydeutera. This appears to be Brachydeutera longipes based on examination of the specimen, now a photo-voucher. Thanks Tom.

Brachydeutera longipes is a relatively recent introduction to North America reported by Mathis & Steiner (1986). They reported it in the United States from Maryland south to Georgia, so this would be a significant range expansion if the identification is correct. Separation from the other species in the northeast, Brachydeutera argentata, can be seen in how sharply delimited the dorsal brown color is from the ventral grayish color. This is not visible in your photo.

Tom, I would like to see more Brachydeutera from your area to confirm this record. I have a number of Brachydeutera argentata from IN and KY to compare against, but it would be good to see a series of specimens to verify the ID.

Brad this is a good record! I'll see if there are any more still out, otherwise I'll have to get more specimens next year.

Moved from Flies. John nailed it. Save for ID if you'd like.

I have it saved

It'll be nice to get one of this genera identified to species.
