To ensure the fertilization, their morphology is well adapted to the proboscis of Lepidoptera, especially Euphydryas, Melanargia, Melitaea, Pieris and Zygaena species.
They include the Silver-washed Fritillary (Argynnis paphia), of which the valenzia form has been found, Purple Hairstreak (Quercusia quercus) and Marbled White (Melanargia golathea).
These sheltered glades provide favourable climatic conditions for butterflies including Marbled White (Melanargia galathea) and Silver-washed Fritillary (Argynnis paphia).
