Purple patch part 1

The adults of several of the Eriocraniidae can be seen by day from about now onwards. Despite being beautiful moths, critical examination is needed to separate many to species level.

The mines of these early flyers will start to appear in April, predominantly on Birch and they can be locally quite abundant.  Tenanted mines can, with care, be identified to species level, but good images are likely to be required by your CMR.

This Eriocrania unimaculella emerged yesterday, reared from a mine collected last April.
