Species Account


Most records are of leaf-mines.

Sutton & Beaumont, 1989: Old records of the atricapitellla group of species are unacceptable due to confusion with allied species (Emmet, MBGBI 1). The present species is probably widespread but at present there are confirmed records only from vice-counties 63 and 64.

2013 (CHF): Mines of the oak-feeding Stigmella species (with the exception of basiguttella are not safely separated without breeding the adults. Some of the dots on the map are unconfirmed but this species is probably more widespread in the county than records suggest. The egg can be laid on either side of the leaf and is usually well away from the leaf margin. The mine is a short, rather broad and quite tortuous corridor. In the first half the frass forms a very narrow central line; in the second half the frass is dispersed more widely, but never filling more than one third of the width of the gallery.
