Taxonomy:   Micro   >>  Gracillariidae  >> Gracillariinae
Other Name/s: Feathered Slender
ID Difficulty:  Red – difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required.
Confusion Species: Mine – similar to Gracillaria syringella
ID pointers: Graham Finch’s specimen was determined via Gen. Det. ID features are a forewing ground colour whitish, with brownish markings, usually visible as three incomplete oblique cross-bands. Cilia distinctly banded light and dark. Tufted labial palps -No other Caloptilia shows that feature (apart from Povolnya leucapennella which is completely different.)
Distribution:  (Last record: 22 April 2025 at Cromford )  –  Unknown and insufficient data. These photos by Graham Finch appear to be the first VC57 record and documented data on this species. A second record was recorded by Clive Ashton on 22nd April 2025 from his Cromford garden.
Flight Period: January /  February /  March /  April /  May /  June /  September /  October /  November /  December /  –  On the wing from September – June. They overwinter, as adult.

Bedrock Geology ** indirectly affects moth distribution by influencing the type of habitat and food plants available in an area. In turn, this may affect the types of moths that can thrive, or where they can most likely be found.

Land-cover * shows the variety of land-cover within the VC57 area, based on the CORINE (Coordination of Information on the Environment) forty-four thematic classes of land-cover. This will show, to a greater or lesser degree, the number and variety of moths found in different land-cover types. The UK continues to operate within the Copernicus programme, with the UK Centre for Ecology & Hydrology (UKCEH) providing Corine Land Cover (CLC) datasets for the UK and its territories.
