Wingspan 7 to 8 mm. A tiny whitish moth with some yellowish suffusion and a distinct black spot near the wing apex.
Leafmine occurs on Lombardy Poplar and Black Poplar http://www.leafmines.co.uk/html/Lepidoptera/P.unipunctella.htm
Where the larval foodplants occur.
The adults fly in July and from September onwards, overwintering sometimes in haystacks.
The larva creates a very distinctive feeding pattern on the leaves of Poplar (Populus). The mine is a long, winding shiny 'snail-trail' caused by the slight raising of the epidermis. There is no visible frass, and the larva pupates at the edge of a leaf, causing it to curl.
It is fairly common in most of England, becoming scarcer further north. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as common.
It appears to be uncommon in Leicestershire and Rutland, where there are few records. L&R Moth Group status = D (rare or rarely recorded).
