Large white blotch, starting at the leaf margin, often strongly disfiguring the still young leaf. Frass in long threads or dispersed. Often several larvae in a mine. Pupation external.

host plants

Betulaceae; oligophagous

Alnus viridis; Carpinus betulus; Corylus avellana; Ostrya.

Records in the literature from Alnus viridis may concern the relatively late described Eriocrania alpinella.


Larvae in May (Hering, 1957a).


BE recorded (Phegea, 2009).

NE the pictures by Maarten Immerzeel above, from April 2017, mean the first observation in the Netherlands.

LUX not recorded (Fauna Europaea, 2009).

distribution within Europe

From Finland to the Pyrenees and Italy, and from Ireland to Romania (Fauna Europaea, 2009).



Eriocrania, Heringocrania chrysolepidella.


According to the literature, the frass pattern consists of long threads. As is shown by the pictures above, both in Carpinus and Corylus the frass may rather be granular and clumped.
