Acleris notana (Donovan, 1806) Species
Last modified: March 28, 2024, 3:20 p.m.
A very rare species in Belgium. Can be confused with the more common Acleris ferrugana and therefore it is best to check the genitalia.
The current distribution (after 2004) is based only on individuals that have been checked for genitalia.
