Yeehaw!!! is all I can say. There were two of these at a lighted sheet (mercury vapor lamp) set up by graduate students from Duke University as part of a field trip. We had thought it was a moth, but one of the students voiced the opinion that it was a neuopteran. I got good photos of this one, and managed to photograph the other one (both males, with the pectinate antennae) against a scale. Wingspan was 7 mm, body length 3 mm (without antennae).

Now the title illustration for the Tree of Life page on Dilaridae.

Also a little point of interest for me is that this is not in Brimley's Insects of North Carolina (1). Despite it being published in 1938, the collecting was done over a very long period, and it is unusual that I find a species not included in it.
