Coptodisca adult reared from leafminer of Populus fremontii. See associated observation of the larva and pupa at https://www.inaturalist.org/observations/99741430

The blurry photo in fourth position here is of the moth in its most pristine state; unfortunately, it afterward lost some scales, particularly of the fringe, during my attempts to photograph it.

In the photo beside the ruler, the moth is not lying flat, thus the measurement is inexact. ~2 mm total length is probably correct.

The moth pupated in a sealed container outdoors and was found alive at this date, so eclosion was presumably recent.
