Caloptilia elongella Linnaeus, 1761
Pale Red Slender

Family: Gracillariidae
Checklist Number: 15.004

A species associated with alder (Alnus glutinosa) and is therefore relatively scarce in the islands. There are two generations per year with the adults present in June and September, overwintering as adults.

The larvae initially feed in a leaf mine and then emerge and form a longtitudinal leaf roll
