Relict species of a colder past like Lycaena helle suffer severely from the recent climate warming. Genetic pattern over the western Palearctic distribution range were analysed to obtain evidences on (i) the historical distribution, (ii) postglacial range shifts and retreats, (iii) the recent distribution situation of highly fragmented remnant populations and (iv) possible future trends. (Markers: allozymes, microsatellites, DNA sequences, climate envelope models, morphometry, funded by the Fonds national de la recherche Luxembourg FNR and the Musée national d´histoire naturelle Luxembourg).
