Eriocrania semipurpurella mine

Betula pubescens, Nieuwendam, leaf underside; mine with young larva

Betula pubescens, Hollandsche Rading: very first part of the mine


Oviposition a few mm from the leaf margin; here begins a corridor of some mm, filled with granular frass. This corridor suddenly widens into a large full depth white blotch, with frass in long threads. The blotch remains adjacent to the leaf margin, and often engulfs the initial corridor. Almost always one larva in the mine (unless by coalescence of two mines). The larva lies venter-down in the mine. Pupation external. Older mines wither and disintegrate, and cannot be found later in the summer.
