Abstract
BackgroundThe scarce fritillary Euphydryas (Hypodryas) maturna (L.) is included in the Habitats Directive's Annexes II and IV(a). Therefore, it is crucially important to be able to define the habitat and breeding places of E. maturna in a correct and unbiased way.New informationData on a previously unknown pre-diapause main host plant, the small cow-wheat (Melampyrum sylvaticum L.), of Euphydryas maturna in Finland is presented.
Highlights
The scarce fritillary Euphydryas (Hypodryas) maturna (Linnaeus, 1758) is a high-profile species within the European Union, as it has been included in the Habitats Directive's (Council Directive 92/43/EEC of 21 May 1992 on the conservation of natural habitats and of wild fauna and flora) Annexes II and IV(a)
The regional host plant use of E. maturna is highly variable throughout its range (Table 1), but is apparently restricted to only a couple of preferred species used for oviposition within any particular region
Fraxinus is the most regularly used oviposition-plant genus in the Central Europe (e.g. Cizek and Konvicka 2005, Levente 2005, Freese et al 2006, Dolek et al 2013), whereas lower plants such as Veronica longifolia are often used in the eastern areas (e.g. Korshunov and Gorbunov 1995, Gorbunov and Kosterin 2007)
