Erebia gorge. (50)
Erebia gorge (Hübner, 1804)
Silky Ringlet, Seidenglanz-Mohrenfalter, Moiré chamoisé, ...
Wingspan: 34 – 38 mm.
During the few short weeks of summer at high elevations close to the glaciers of Oetztal valley, there is an unexpected variety of life to be observed.
Numerous moths, burnets in good numbers, and also several species of butterflies, some of them endemic to those elevations - like some dark ones that followed my path through lonesome and silent places far above the treeline.
Erebia gorge, the Silky Ringlet, is described to be a complex species with a varienty of different patterns. Fresh specimens would often show a silky appearance. Erebia gorge may be found in the Pyrenees, the western and central Alpine chain, in Slovenia, Gran Sasso in Italy, the Velebit, Carpatians, Tatra. It is confined to elevations between 1800 and 3000m.
Caterpillars feed on grass such as Festuca alpina, and Poa minor.
At an elevation of 2650m near Vernagt glacier -
close to the place of previous posting on Nigritella.

|Upper Vernagt valley with strongly receded Vernagt glacier. Erebia gorge was seen along the path at the opposite slope, quite close to Vernagt refuge (2760m a.s.l.) which can be seen here in the distance. Hiking up there from the nearest human dwellings - the small village of Vent (1900m a.s.l.), or the lonesome and exposed ancient farmhouses of Rofen (2050m a.s.l.) - takes about 3 hours. A complete roundtrip leading into the highest parts of Rofen valley and back to Vent will take about 8-10 hours, most of the time high above the treeline, and very awarding to enjoy a scenery of eternal ice, and to study the alpine nature. That day, it took me even a bit longer, taking dozens of pictures of plants, butterflies, and others ... |
