The caterpillars are colored black brown, have a yellowish, brown dashed back line as well as black, yellow framed spot rows and short yellow-white bristles. The doll has a brown- gray color with a dark drawing and a compact shape.
Similar Species
The alpine meadows Fritillary resembles some other Perlmutterfalterarten, in particular the following:
- Similar Fritillary ( Boloria napaea ). The males are slightly larger, while the larger females also are easy to distinguish because of their often purple -brown or green-brown top color and show a more yellow -green colored hindwing underside.
- Boloria graeca is a slightly larger species whose hind wing underside brighter and more is yellowish.
- Raised bog fritillary ( Boloria aquilonaris ). The moths are breitflügeliger with more rounded hind wings. The black drawing is something distinctive and powerful.
- Snake root Fritillary ( Boloria titania ). The drawing on the front is striking and somewhat darker colored the underside of the hind wings strong rust.
- Alpine Fritillary ( Boloria Thore ). The species has much darker, merging into each other drawing elements on the wing fronts.
- Magerrasen Fritillary ( Boloria dia). The moths are usually smaller and drawn strong.
- Meadowsweet Fritillary ( Brenthis ino ). The moths are larger, have strikingly rounded wings and a paler, less pronounced Rotzeichnung on the hind wings back.
In order for the determination still be safe, specialists should be consulted.
Distribution and habitat
The presence of the species extends from the Cantabrian Mountains and the Pyrenees through the Alps and the Apennines east to the Balkans, the Carpathians, the Caucasus and Central Asia to western China. It is found at altitudes between 1500 and 3000 meters on mountain pastures.
Way of life
The moths live in a generation from late June to August. They fly in a swirling flight over flower-filled alpine meadows close to the ground. The caterpillars live polyphagous on low plants, but prefer violet species ( Viola ) and hibernate. They pupate on or under rocks.
Endangering
The species occurs in Germany only in the Bavarian Alps before, can at certain points be quite numerous, and is performed on the Red List of endangered species in category R ( kind of geographical restriction ).
