Erebia cassioides.

Erebia cassioides (Reiner & Hochenwarth, 1792)
Common Brassy Ringlet
Moiré lustré

Genus: Erebia
Subfamily: Satyrinae
Family: Nymphalidae

Wing span 34 – 38 mm.

Never before I have seen ringlets with such a brilliant iridescence as during my hikes at Grossglockner in the Tyrol in August 2006.

When those ringlets came to sit down on my path in the sun, their iridescence was so strikingly brilliant they reminded me of tropical Morpho butterflies – that in fact may be closely related to the Satyriinae subfamily anyway, showing lustre on the upper sides and good numbers of well developed eye spots on the undersides of wings.

Observed on mountain hikes to various locations in the highest regions of Austria’s Hohe Tauern National Park to the end of August, the species seem to be Erebia cassioides, the Common Brassy Ringlet.

First described from the mountains of Heiligenblut in Carinthia, Austria, Erebia cassioides is showing the widest distribution of all members of the tyndarus group of brassy ringlets. It is reported from the Pyrenees, from two isolated areas of the Alps in the southwest and the east, and from various mountain locations at the Balkan.

The species inhabits grassy spots between rocks at high elevations between 1600m and 2600m. Butterflies are on their wings in one extended generation from July to September. Caterpillars feed on grass: Festuca ovina.

To compare with other Brassy Ringlets of “tyndarus group”:

> Erebia tyndarus: No eye spots on hindwings.
> Erebia nivalis: Tiny eye spots on forewing; orange spots around eye spots on forewings extending into the centre of wing.

Hi Peter,
Beautiful metallic colours in the wings.
Well done

Hello Peter!
I really have to say that thanks to your picture I learned a lot about Erebia genus. Very good idea for series (maybe you should make a new theme like "European Erebia species"?), very useful and helpful!
In this picture I especially like the mosaic of colours on its wings (even if there are not to many). POV and DOF as always are good, and a note - very professional.
Best greetings,

Hi Peter,
Splendid shot of the Brassy Ringlet. Superb mettalic colours and lustre. POV is very illustrative and the brown earth presents a fine contrasts. Very nicely composed. Kudos.

Hi, dear Peter.
Amazing note. I have read it with great interest. Thank you very much.
You are right. This photos reflects the colour features (as many others) of this beautiful butterfly perfectly and your note helps to see them. I do not cease to be surprised how you managed to reproduce the smallest details of pictured objects. Superb work, TFS and my best regards.

Hi Peter,
I like this metallic iridescence that shows how well Nature handle light interference to make colors. Perfect details and the exact angle to view the phenomenon.
TFS and best regards, José M.

I would like to know how you distinguish one Erebia from another, they are so similar! Excellent job, Peter, very sharp and clear and with a great interest.
My compliments and TFS.

Hallo Peter,
Prachtvoll die schillernde Bordüre dieses Mohrenfalters.Da musst Du dich wohl nach dem Licht richten um diesen Effekt zu fotografieren.Wir sind Dir alle so dankbar, diese Serie gebracht zu haben. Dank den Vergleichsmöglichkeiten, kann man die verschiedenen Arten jetzt ziemlich gut unterscheiden, was ich an Hand von kleinen Zeichnungen in den Sachbüchern einfach nicht kann.
Mit bestem Dank. Wünsche noch einen schönen Abend

Hallo Peter,
danke für den brillianten cassioides. Die Zeichnungen, insbesondere auch der Schillereffekt, sind auf dem linken Vorderflügel besonders scharf und deutlich. Kopf-, Thorax- und Abdomenstrukturen sind nicht so deutlich aufgelöst. Liegt das an der weiten Blendenöffnung oder an Bewegungen des Falters?
Schöne Grüße, Peter
