Stigmella lapponica (Wocke, 1862)

drab birch pigmy

Stigmella lapponica mine

Betula pubescens, Bergen NH

same mine, detail

mine

Oviposition generally at the underside of the leaf. The mine is a slender corridor that hardly widens, even towards the end. The first third is stuffed with diffuse greenish brown frass. After a moult the frass pattern changes completely, into a very narrow, continuous black line. The mine often follows a thick vein over a long distance, but the larva is capable of crossing thick veins, even the midrib.
