Broad-barred Midget

Probably the scarcest of the four Phyllonorycter species mining common alder <i>Alnus glutinosa</i>, but still fairly widespread where the foodplant is found, and probably more evenly distributed across the county than the distribution map currently suggests.

Elm Midget

The commoner of the two Phyllonorycters mining elm, and probably to be found everywhere in the county where elm occurs.&nbsp; Possibly absent from the Levels and the moorland districts of Exmoor, owing to the lack of its hostplant.

Small Alder Midget

A widespread and moderately common miner of alders.

Phyllonorycter stettinensis

Lesser Alder Leaf-miner
