The paper provides an overview on the distribution of recently discovered Scarce Large Blue (Phengaris (Maculinea) teleius) in northern Serbia (Selevenj Sands, Ludaš Lake and Subotica
Sands). Mapping of the butterfly and its habitat has shown that most of the suitable habitats are limited to protected areas where at least some of the wet meadows with Sanguisorba
officinalis host plant are suitably managed and regularly mown. Given the known maximum dispersal distances of P. teleius, the suitable habitat patches possibly support two separate meta-populations. Fragmentation and isolation of remaining colonies represent the main threats to long term survival of the species in Serbia. Based on IUCN criteria for regional red lists, the species qualifies as Endangered (EN) in Serbia and requires immediate conservation actions. Our results suggest that mowing is of high importance for maintaining suitable habitat. Until more is known about local ecological requirements
of the species, general mowing recommendations should be followed with avoidance of mowing between mid June and mid September and providing a mosaic of different mowing regimes
