3.1. Nahrung der Raupe

• [Betulaceae:] Betula nana (Zwerg-Birke)

Die Art kommt in Großbritannien nur in den Highlands von Schottland vor. Nach Agassiz (1996: 58) lebt die Raupe dort an der Zwerg-Birke, Betula pendula. Die Art war dort zunächst von Stainton (1871: 96-97) entdeckt und als "Swammerdamia nanivora" beschrieben worden: "From the Swammerdamia larva on Betula nana found by Dr. F. Buchanan White in Strathglass Inverness-shire, in September, 1869(see Ent. Ann. 1870), p. 4; E. M. M. vol. vii. p. 51), I bred a specimen, which accords with none of our existing species. Except in its much smaller size (nearly of the size of S. pyrella), it has considerable resemblance with a species from Southern Russia, which I have received from Dr. Staudinger under the name of S. ornichella. [...] My readers will not expect me to describe a new Swammerdamia from a single specimen, but the larva was so different from that of S. griseocapitella, that I apprehend there can be no difficulty in pronouncing it that of a distinct species, and I therefore append a description of the larva received on the 18th September, 1869, from Dr. F. Buchanan White,and which was unfortunately so near pupation that I had no time to get it figured. [...] Makes a web on the twig of Betula nana, and gnaws the leaves. I hope those who have the opportunity of collecting amongst Betula nana will bear this insect in mind."

Stainton kannte aber anscheinend die "Oecophora passerella Zetterstedt, 1839" vom Hohen Norden Lapplands nicht. Zu der heißt es jetzt bei Bengtsson & Johansson (2011: 285): "Larva on Betula nana, first mining, later feeding externally beneath a web (occasionally shared by several larvae). Occurs on moors with Betula nana, both in lowland and subalpine areas. Disjunct distribution in the northern two thirds of Sweden."
