Leafmine on Oak and Hornbeam http://www.leafmines.co.uk/html/Lepidoptera/B.ulmella2.htm
Areas where Oak or Hornbeam are present.
Leaf-mine: July, September and October. Adults are found mainly in July and October.
The larva feeds on Oak and Hornbeam, in conflict with the misapplied scientific name ulmella which suggests it feeds on Elm. The mine is a short contorted gallery close to the midrib of a leaf, containing broken black frass. When pupating, in common with other Bucculatrix species, the larva creates a distinctive ribbed cocoon surrounded by a 'palisade' of vertical silken hairs.
A fairly common species over England, Wales and Scotland, though like many of its genus probably overlooked. 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).
