Caloptilia falconipennella

(Hübner, [1813])

---

Wingspan c. 13mm.

This is a rather rare and local species that is not often observed. Records suggest it has a fairly broad distribution, but is probably overlooked and may be more widespread than is currently known.

The larvae feed on alder (Alnus glutinosa), at first mining the leaf and then creating a small number of folds on the leaf-edge, feeding within.

The adult moths emerge in September and overwinter in this stage, reappearing in the spring.
