Fritillary fulfilment

Spurred on by my lifer Western Orphean Warbler and Green-winged Orchid, a couple of days later I had a go at trying to add Glanville Fritillary to my butterfly list.  This is an endangered and scarce butterfly in Belgium with only a handful of isolated populations, one of which is within walking distance of Lommel train station.  As soon as I got to the area, I immediately spotted a pair copulating and I spent the next hour or so surrounded by perhaps a dozen of them, taking plenty of pictures of these beauties.  Getting a photograph with the wings open was difficult, but I persevered, although the underside is actually more distinctive on this species, as it is with most fritillaries.
