    When to see it

    Life History

    The larva feeds on Field Maple and folds the tip of a leaf lobe downwards to create a distinctive and easy-to find mine. Occasionally the mine is not on the leaf edge, but forms a crease in the leaf.  Leaf mines can be located during July and more commonly in September and October.

    UK Status

    The species is distributed over much of England where the food plant is natively established. It is slowly expanding northwards into areas where the tree is introduced. In the Butterfly Conservation’s Microlepidoptera Report 2011 this species was classified as common.
