Morley’s Final Catalogue: Not listed

Recent Status: The moth was first recorded in Suffolk in 2013. It has established and spread. It may also reach Suffolk as an immigrant.

Life Style: A double brooded species that hibernates. It can be found throughout the year. The larvae feed on Acer species leaves, primarily A. campestre.

Identification: Caloptilia species stand erect on their front legs at rest. C. hemidactylella is a light orange brown with yellow markings. There is a prominent yellow costal blotch with the basal patch darker especially as an edge to the costal blotch. There is variable yellow shading particularly along the costa beyond the blotch. The costa is commonly spotted. The femur and tibia of the front legs are a similar colour to the wings. It can be similar to forms of C. betulicola however C. betulicola has palps a similar colour to the wings with a pale tip. The palps of C. hemidactylella are pale with a dark band.
The larvae mine a gallery leading to a blotch and then leave this to form a conical rolled leaf. They will move several times. They pupate in a silken cocoon lightly covered with a silk membrane on the underside of a leaf. More Info

Retained Specimen / Photograph will be Required.
