Eriocrania sangii - Eriocrania sangii
Wingspan 9 to 14 mm. A small purple and gold moth, there are similar species and detailed examination is required for a safe id.
Well wooded areas containing Birch.
The adults fly in March and April.
The larva creates a blotch mine in a leaf of birch (Betula), rather like some related species, but unlike the other species, the larva itself is dark grey and is quite distinctive if the mined leaf is held up to the light.
Locally frequent, especially in northern England. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as local.
It appears to be uncommon in Leicestershire and Rutland, where there are few records. L&R Moth Group status = D (rare or rarely recorded).
