Ectoedemia agrimoniae

Ectoedemia agrimoniae is a moth of the Nepticulidae family. It is found from Fennoscandia to the Pyrenees, Italy and Greece, and from Great Britain to Ukraine.

The wingspan is 4-6.4 mm. Adults are on wing from May to July. There is one generation per year.

The larvae feed on Agrimonia eupatoria and Aremonia agrimonioides. They mine the leaves of their host plant. The mine consists of a strongly contorted narrow corridor with a linear interrupted frass line. Later, the mine becomes a broad corridor or elongated blotch with dispsered frass. There are often multiple mines in a single leaf. Pupation takes place inside of the mine, in a violet to blackish cocoon.
