Description: Adult ( Figs 23 –24). Wingspan 14–17 mm, ground colour blackish brown, usually interspersed by pale brown arches forming 3 diffuse and irregular transverse bands ( Fig. 23 ) or whole forewing very diffuse blackish brown (Fig. 24). Differs by its small size from most other Depressaria species.

Bionomics: Larva on Apiaceae , e.g. Daucus carota L. and

Foeniculum vulgare MILL.

Distribution: Azores Islands (new record), Madeira (new

record). Widespread in South Europe and North Africa.

Diagnosis: The form with transverse fasciae is usually very distinct, but forms with more or less uniform forewings may be confused with different other species, including some non-Depressariidae (especially of Gelechiidae ) which, however, have a more or less distinct emargination at the termen of the hindwing. Moreover the labial palps ( Fig. 25 ) can help to exclude Gelechiidae and the genitalia (Figs 26, 27) in both sexes are characteristic.
