First observation for Belgium was during 2009 in LX. Nowadays it is still a rare species in our country.
The larva is green.
The larva makes a short slender gallery that is generally confined to a small area of the leaf. The frass is linear throughout.

The adults fly in one generation a year, mainly during May and June.
