Dead lunch?
2011-06-28  I rode my bicycle through our nearest natural park - the Lobau, in Vienna's 22nd district.  I guess I spent as much time taking pictures as cycling.  There were several of these butterflies (Argynnis paphia - Kaisermantel - Silver-washed Fritillary) obsessed with this dead leaf.  I assume there was still some sap in the leaf and that it was a bit intoxicating.

Update:  a bit of web browsing came up with the fact that the by-product of some molds is alcohol, and that butterflies can get drunk on alcohol.  That's probably what is happening here.

Many thanks for your comments on the model of Vienna.  I didn't get around to putting up a picture yesterday
