Morley’s Final Catalogue: Not listed.

Recent Status: Few Suffolk records.

Life Style: The species is single brooded flying in June and July. The larvae feed on Ulmus leaves. They hibernate fully fed or may continue feeding the following spring before pupating attached to a stem.

Identification: The moth resembles C. milvipennis which is common in Suffolk as well as C. alnifoliae and C. adjectella. It is light ochre with a pale costal streak from the base. It can be identified by genitalia dissection. The males are quite difficult by this means and it should be noted that the images of the male genitalia in the Moths and Butterflies of Great Britain and Ireland are incorrectly labelled in reverse.
The larvae initially mine a straight gallery in a leaf before constructing a case from an oval of the leaf at the exit hole. They then mine from their portable case which is later constructed from a leaf edge. The case shape is quite variable. More Info

	Determination by Genitalia Examination (gen. det.) Required
