The only times I have seen petropolitana were in June 2005 when it appeared in healthy colonies in both the Basses Alpes (around 1300m) and the Hautes-Alpes at 2000m, and then not again until 2010, but every year subsequently in a variety of different locations. It is a butterfly of medium altitudes and relatively early emergence, the flight period being May-July.
|It can de identified for certain by the uph transverse discal line, which does not occur in the very similar male of the Large Wall (L. maera) with which it could otherwise easily be confused.|

a male, clearly at the end of the flight period.

|25509||F||a female, as indicated by the more extensive orange markings, as well as the body shape.||1320|
|25527||M||an underside of a rather worn male, looking as if it is at the end of the flight period.||1320|
