Species Account

Most records are of leaf-mines.

Sutton & Beaumont, 1989: Unrecorded prior to 1975 but has since proved to be widespread and fairly common with records from all five vice-counties.

2013 (CHF): Mines on birch are fairly common across the county but care must be taken to distinguish this from the other Stigmella species mining birch. The name confusella refers to trouble separating it from Stigmella lapponica however the mines are quite different and should not cause too much confusion as lapponica has cloudy green frass in the early part of the mine. The mine is a very long and slender gallery which hardly widens at all. The frass is in a continuous central line which may follow veins over long distances, making it look angular.
