Encyclopedia
Ectoedemia liebwerdella is a moth
of the Nepticulidae
family. It occurs locally in central and southern Europe
, east to the Volga and Ural regions of Russia
.
The wingspan
is 6.6–8 mm. The larvae normally have a two-year cycle, they feed during two summers and overwinter twice to pupate in May–July. Adults are on wing from early July to August.
The larvae feed on various Fagus
and Quercus species. Unlike most other Nepticulidae
species, the larvae mine the bark of their host, rather than the leaves. The mine consists of a contorted gallery in bark of trunks or thick branches. The larva feeds mainly in the direction of the main axis. It is especially abundant on the sunny side of trees.
