Mompha ochraceella

Description

Mompha ochraceella is a moth of the Momphidae family. It is found in most of Europe, ranging (in the south) to Morocco and Asia Minor. In the east, the range extends to the Caucasus and Iran. The wingspan is 14–16 mm. Adults are on wing from May to August. The larvae feed on Epilobium species, including Epilobium hirsutum. They mine the stems and later the leaves of their host plant. The leaf mine consists of a lower-surface blotch in a low growing leaf. The blotch is centered over the midrib. The mine contains little or no frass.
