Wingspan 6 to 8 mm.
Leafmine occurs on Hornbeam. http://www.leafmines.co.uk/html/Lepidoptera/P.tenerella.htm
Where Hornbeam, the larval foodplant occurs.
The adults fly in two generations, in May then again during July and August.
The larva creates a narrow mine on the underside of a leaf of Hornbeam (Carpinus), which can be confused with other hornbeam feeding species.
Distributed mainly in the south-east of England, P. tenerella has been occasionally found elsewhere, probably as an introduction with the foodplant. 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).
