of the Lepidoptera of Belgium

Chrysoesthia drurella (Fabricius, 1775)

Observed in many areas in Belgium, but never frequent.

The larva makes a mine in the leaves of Chenopodium and Atriplex species. The gallery is sometimes contorted to such an extent that a blotch mine is formed. The larvae of the autumn generation hibernate full-fed in a cocoon which it leaves before pupating. Pupation in detritus at ground level. Larvae of the spring generation do not form a cocoon.

The adults have been observed during May and June and again from late July till September.
