Caloptilia falconipennella

Alternative names
Scarce Alder Slender
Description

Wingspan about 13mm.

Identification difficulty
Habitat

Areas where alder is present.

When to see it

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

Life History

The larvae feed on alder, at first mining the leaf and creating a small, tent-like edge mine and then making a small number of folds on the leaf-edge which are 'anchored down' with silken strands.  The larva feeds within.

UK Status

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. In the Butterfly Conservation’s Microlepidoptera Report 2011 this species was classified as Nationally Scarce B.

VC55 Status

It appears to be uncommon in Leicestershire and Rutland, where there are few records. L&R Moth Group status = D (rare or rarely recorded).
