Sažetak
Butterflies of genus Phengaris are parasites within nests of red Myrmica ants. Due to their specific life-cycle and habitat loss, they are highly endangered throughout Europe. The aim of this study was to define the distribution and key factors affecting the abundance of two highly endangered large blue butterflies, Phengaris telejus and Phengaris nausithous in Croatia. They often occur in sympatry and have similar habitat requirements. In Croatia P. telejus is more widespread and abundant than M. nausithous. For understanding their ecology more data is needed on population biology and microhabitat preferences of both species. Adult butterfly and catepillar numbers, food-plant, ant community and different abiotic factors including soil chemistry were studied within the protected landscape Bedekovićeve grabe near Čakovec, northern Croatia. The overall results showed that the density of P. telejus is associated with plant density, but not with height or bud size. Contrary these results, density of P. nausithous is limited with the presence of the host ant M. rubra and suitable microhabitat conditions that omit their survival. It has been concluded that populations of both species are stable within the site, but low mobility and bad management could reduce the effective population size. Habitat management should focus on the maintenance of different microhabitats that hold both species and resources, demanding some flexibility in mowing regimes.
