Eudonia delunella (Stainton, 1849) Species

Last modified: Oct. 20, 2023, 12:48 p.m.

Used to be a very rare species in Belgium, only known from very old observations in two provinces. It was thought to be extinct but an observation in 2006 in OV refutes this. Nowadays (2010) it is a fairly common species throughout Belgium, especially in the northern part.
