“…Since the different life stages of butterflies have different resource requirements, detailed ecological studies of each stage are needed in order to define a species' requirements in terms of the functional resourcebased concept (Dennis, 2003). As the availability of resources for adults affects their behaviour (e.g., Turlure & Van Dyck, 2009;Ide, 2010), spatial distribution (e.g., Loertscher et al, 1995;Krauss et al, 2005), movements (e.g., Brommer & Fred, 1999;Schneider et al, 2003) and demographic parameters (e.g., Luoto et al, 2001;Auckland et al, 2004;Junker & Schmitt, 2010), it is important to have a good knowledge of adult ecology when designing an appropriate management policy for the longterm survival of a target species. Since Z. polyxena utilizes the same plant species (Aristolochia spp.)…”
