Recent Status: A common species that is poorly recorded in Suffolk, probably owing to identification constraints.
Life Style: A single brooded species, flying from May to July that comes to light. The larvae mine leaves of Betula and have also been recorded on Carpinus. They hibernate and may feed the following spring before pupation.
Identification: The moth is a light ochre with a paler base to the costa. There are several similar species. They can be identified by dissection but this is not easy particularly for the males. It should be noted that the images of the male genitalia in the Moths and Butterflies of Great Britain and Ireland for C. milvipennis and C. badiipennella are wrongly labelled in reverse. More Info The first larval case is constructed from an initial mined blotch. The larvae then mine from the underside of a leaf and construct subsequent cases from leaf edges resulting in a laterally compressed relatively slender case with a dorsal keel equating to the leaf serrations. Three such cases may be constructed. The oral opening is set at around 45 degrees.
