Depressaria depressana
Purple Carrot-seed Moth, Blunt's Flat-body
Depressaria depressana is a small moth in the family Depressariidae, native to Eurasia and introduced to North America around 2008–2009. It is a family-level specialist herbivore of Apiaceae, feeding on reproductive structures of wild carrot, parsnip, and related umbellifers. The species has undergone rapid range expansion in eastern North America, exhibiting higher genetic diversity and dispersal capacity than its congener D. radiella. Adults are active from spring through early fall with multiple generations per year in warmer regions.
