Brenthis hecate
Brenthis hecate is a large fritillary with a wingspan reaching 35–45 millimetres (1.4–1.8 in) and bright orange uppersides of the wings. The underside of the hindwings show a double parallel line of brown spots (hence the common name). The flight period extends from May to early August. The larva feeds on Filipendula ulmaria and Dorycnium.
This species is typical of dry flowery meadows with light scrub and woodland margins, at an elevation of 25–1,500 metres (82–4,900 ft) a.s.l.. Brenthis hecate is found in South-West Europe, South Russia, the Balkans, Asia Minor, Iran and Central Asia.
Looks like it could be some sort of fritillary but I am no expert. Maybe you find it here?
