Stigmella hemargyrella: Distribution map

Please note that the NBN Gateway map service has been terminated as of 1 April 2017.

As soon as a replacement map service is available, distribution maps will hopefully appear here again.

In the meantime, you can get some idea of distribution from the NBN Atlas website.

Stigmella hemargyrella

(Kollar, 1832)


Wingspan 5-6 mm.

Like many of its congeners, this species is more easily identified by the structure of the leafmine created by the larva. In this case, the foodplant is beech (Fagus sylvatica), and the mine is a sinuous gallery with the frass forming a coil part way through the mine.

The species is fairly common over much of Britain, flying in two generations, April and May, and later in July and August.

The adults are small and dark, with a pale patch centrally on the forewing, and with a wingspan of only around 6mm.
