Species and mate recognition in two sympatric Grayling butterflies: Hipparchia fagi and H. hermione genava (Lepidoptera)

摘要: The main aim of this study was to investigate and compare the patterns male courtship behaviour in Hipparchia fagi (Woodland Grayling) H. hermione genava (Rock order determine if premating barriers are involved reproductive isolation between two sympatric syntopic species. Although they show a similar pattern sexual (perching, flight pursuit, courtship), there were significant quantitative inter-specific differences step Bowing. During step, bashes strokes female antennae his forewings on androconial scales revealing importance scent stimuli mate communication. Moreover, different signals, spanning several sensory modalities (visual, chemical, tactile stimuli) spatio-temporal (during pair step), might serve as In particular, both males females (a woodland habitat specialist) seem take less time recogni...
