About Brenthis daphne (Denis & Schiffermüller), 1775
Brenthis daphne (Denis & Schiffermüller), 1775 has a wingspan of 30–44 millimetres (1.2–1.7 in). Its wings are rather rounded; the upperside of the forewings has a bright orange base color, with an incomplete black marginal band. The underside of the hindwings features a yellowish postdiscal band, and the marginal area is completely suffused with purple to create a marble effect, which gives this species its common name. The quadrangular patch on the underside of the hindwing is partially shaded orange-pink toward its outer side. The chrysalis has two dorsal rows of thorns that bear bright spots and a bright metallic shine. This species is very similar to the lesser marbled fritillary (Brenthis ino), but Brenthis ino is slightly smaller and has the same quadrangular patch completely colored yellow. This widespread species occurs in the Palearctic realm, ranging from the southern parts of continental Europe (including northern Spain, southern France, Germany, Italy, and extending east to Slovakia and Greece) to the Caucasus, western Siberia, Korea, and Japan. It lives in warm, sunny forest edges, woodlands, and bushy areas where its host plants grow, at elevations between 75 and 1,750 metres (246–5,741 ft) above sea level.
