Catalogue
of the Lepidoptera of Belgium


Caloptilia cuculipennella (Hübner, 1796)

A rare species in Belgium. With the present knowledge of leafmines, more frequently observed than in the past.

The larvae feed on Ligustrum vulgare, Fraxinus excelsior and Syringa vulgaris. Initially an epidermal mine on the upper surface of the leaf, later the mine starts to contract and the leaf concealing the mine. Now the larvae leave the mine and live freely in a downwards rolled leaflet. Pupation in a flimsy white cocoon, attached hammock-wise within the final cone.

The adults fly in one generation a year; emerging during September, overwintering and then flying until May. The moths are active during late afternoon around its food plant and later comes to light.
