In many places, the UK in particular, the Pearl-bordered Fritillary (B. euphrosyne) is considerably less common than selene. However, in southern France the reverse seems to be true, and in Var and the Alpes-Maritimes selene does not occur so there is never an identification problem. In fact, having visited a variety of locations in southern France in the past seven years I have not seen a single selene, and euphrosyne was often common, sometimes very common. In 2011 and 2012 I encountered selene at a location in the Jura.

In 2017 I visited the département of Lozčre in south central France, a rather wild and uncultivated region. At a lakeside location the weather was overcast and very little was flying except for a few Erebia ringlets, but the sun eventually came out and the whole area was suddenly filled with butterflies, including nine different species of Fritillary, including numerous selene.

 

Selene is superficially quite similar to euphrosyne. The principal differences are discussed on the euphrosyne page.

observations

alt. m
43664 M a fresh male, posing open-winged in rather overcast conditions. 43670 is the underside. 1340
31086 F a female, from the same location as 27525. It is not as heavily marked as 27525 but the "pearls" at the margins are more clearly enclosed and thus more easily recognised as such. 1060
27525 F a female, as indicated by the body shape, heavier markings and rounder wing shape. 27546 is the underside. 1060
43724 F a female, rather dusky and dull in comparison to the male. 1340
43670 M a male, the underside of 43664, and very crisply marked. 1340
27546 F the series of white discal marks is not particularly pronounced, only the marks in s1c and s4 really appearing white, the others being rather off-white. 27525 is the upperside. 1060
