title: Nectar source distribution as a determinant of oviposition host species in Euphydryas chalcedona.
abstract: The distribution of nectar sources is shown to affect both the distribution of adult Euphydryas chalcedona and their offspring. We suggest that nectar sources thereby influence the selection of oviposition host plant species in habitats where those species are spacially separated.
