Alternative names
Virgin Pigmy
Description

Wingspan about 7 mm. It lacks discrete white spots but does show a suggestion of mid-costal and dorsal white spots; frontal tuft pale ferruginous, collar concolorous; eyecaps white. 

Identification difficulty

Adult Leafmine

Habitat

Where Aspen is present.

When to see it

There is a single generation, and the adults are on the wing in May and June.

Life History

The larva mines the leaves of Aspen (Populus tremula), first galling the leaf petiole, then forming a triangular blotch extending from the midrib. When the leaves change colour in autumn, the mined area often remains a 'green island' even after the leaves have fallen. Parthenogenetic (females only).

UK Status

Locally distributed throughout mainland Britain, though more plentiful in the south. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as local.

VC55 Status

Increasingly well recorded in Leicestershire and Rutland in recent years, particularly from the leafmines on Aspen
