Remarks

Introduced species, first detected in North America in 1869.

Linnaeus in his description of heracliana actually had two species. Bradley (1966) applied heracliana to what is now Agonopterix heracliana (extralimital). To the other species, the name D. pastinacella (Duponchel) was applied. Karsholt et al. (2004), determined that Depressaria radiella (Goeze, 1783: 162) (Phalaena (Tinea)) should have had priority.

Considered invasive in this country (from Europe). (Capinera, John L. North American Vegetable Pests. The Pattern of Invasion. American Entomologist. Spring 2002)
