Fig. 4From: Geographic origin and migration phenology of European red admirals (Vanessa atalanta) as revealed by stable isotopesMeasured δ2H values in the wings of red admirals sampled from the trap captures at Rybachy in 2004 (▲) and 2005 (○). The broken line shows the expected value for locally hatched individuals from the Rybachy region. For details on calculation of this estimate see text and Brattström et al. [14]Back to article page
