Abstract:Larvae of the obligate myrmecophilous social parasite Maculinea alcon (Lepidoptera: Lycaenidae) were found exclusively using Myrmica aloba (Hymenoptera: Formicidae) ant hosts in NE-Portugal. This is the first record of the host ant usage of any Maculinea species in Portugal, and of any Maculinea using M. aloba nests. These results on such peripheral European populations confirm that knowledge of the local host ant species is crucial for the successful protection of these endangered butterflies, and vital for examining the evolution of such interactions.
