Taxonomic history
Originally described as Depressaria pulvipennella by Clemens in 1864; later transferred to Agonopterix.
Flight period note
The exceptionally long activity period (February–October) for a single-brooded suggests adults may be long-lived or enter extended dormancy, though this has not been experimentally confirmed.
