Bryotropha galbanella
(Zeller, 1839)
Bryotropha galbanella is a small gelechiid with a broad distribution across northern Europe, extending eastward to Russia and Japan, and westward to Alaska and extreme north-western Canada. The exhibits in wingspan, with males measuring 14–18 mm and females 13–16 mm. Larvae are specialized feeders on mosses, particularly Dicranum scoparium, and construct silken tubes for shelter. The species has been incorrectly recorded from Chile.
