Agonopterix nanatella aridella (Mann, 1869)

Lepidoptera, Depressariidae

mine

Full depth, little contracted and very transparant blotch, mostly limited to the leaf tip. Most frass is ejected; what remains in the mine are unusually large grains. Not all larvae mine, some live free. Pupation external.

hostplants

Asteraceae, monophagous

Cirsium.

phenology

Larvae in April, May (Hering, 1957a).

distribution within Europe

Amsel & Hering (1933a) mention aridella from Sardinia; Hering (1957a) writes “southern Europe”. The Fauna Europaea (2010) accepts aridella as a valid subspecies of nanatella, but has no information about its distribution.

notes

See also Agonopterix nanatella. Whether indeed the one subspecies is limited to Carlina, the other to Cirsium, remains to be established.
