Stigmella continuella (Stainton, 1856)
Betula pubescens, Overveen
Egg at the underside, often in a vein axil. The mine is a slender, little widening corridor. Its first part is strongly contorted; the leaf tissue that is cut off thereby is killed, mostly resulting in a brown spot. The remainder of the corridor in contrast is very little contorted, often remarkably straight, when it runs alongside a vein. The corridor is almost completely filled with coiled frass, that is green when fresh, brown later. Pupation external.
Betula nana, pendula, pubescens.
Larvae in Britain in June – July and September – October (Emmet, 1983a); in Scandinavia only one generation, with larvae in July – August (Johansson ao, 1990a).
