Morley’s Final Catalogue: Bentley Woods in July 1901 (Pyett); Leiston (Grey); Southwold (Ctw); Lowestoft and Fritton (Bd); bred in June 1929 from case found in Greenacres Lane at Gorleston (Mly).

Recent Status: There are a number of recent records.

Life Style: A single brooded species that flies during June and July. The larvae mine leaves of Ulmus. They may hibernate for two winters before pupation.

Identification: The moth is a greyish ochre with a cream costa to two fifths. They resemble a darker greyer version of the common C. milvipennis. They can be identified by genitalia dissection.
The larvae initially form a short gallery from the oviposition site in the angle between a vein and the mid-vein on the underside of a leaf. They excise a piece from the end of this for their first case. Their second case is cut from the centre of a leaf. They hibernate in this affixed to a twig. In their second year they construct successive cases from leaf margins resulting in bivalve cases with a dorsal keel of the leaf serrated margin. They may then pass a second winter before pupation.
