Identification
Males have exceptionally long palps and a very “dainty” thorax (barely thicker than the head), which means the palps appear to be held well *above* the thorax, not right up against them:

Females have a distinctive “triangular” look from the side, due to the thin thorax, thin head, and tapering palps:

The female’s palps are shorter than those of plumifrontella, but longer than those of female popeanella/propinqua/texanella.
Also usually has a contrastingly dark costa near the base of the forewings.
Range
Common in the Midwest and Southeast, but rare to absent in the Northeast.
