Riassunto - Scoperta di popolazioni isolate di Phengaris alcon e Melitaea diamina nella Pianura Padana centrale (Italia) (Lepidoptera Rhopalocera). all’interno del Parco del Mincio (Mantova, lombardia) sono state scoperte popolazioni di Melitaea diamina (Lang, 1789) e Phengaris alcon ([Denis & Schiffermueller], 1775) (lepidoptera rhopalocera), rispettivamente nell’anno 2008 e 2010. entrambe le specie non sono note per la Pianura Padana, e le popolazioni più vicine conosciute si trovano a 170 e 50 km, rispettivamente per P. alcon e M. diamina. Durante l’anno 2011 sono state svolte ulteriori indagini su queste nuove popolazioni. entrambe le specie sono state riscontrate esclusivamente in prati umidi, di cui sono considerate specie tipiche. le nuove popolazioni dovranno essere protette, garantendo il mantenimento in futuro dei prati umidi mediante sfalcio.
Abstract - Populations of Melitaea diamina (Lang, 1789) and Phengaris alcon ([Denis & Schiffermueller], 1775) (lepidoptera rhopalocera) were discovered in the Mincio natural Park (Mantua province, lombardy) in the years 2008 and 2010, respectively. Both species had not been known from the central Po Plain and the closest populations are approximately 170 km and 50 km away for P. alcon and M. diamina, respectively. More data on the new populations were collected during the year 2011. Both species were exclusively found in wet meadows, for which they are considered typical. The newly discovered populations need to be protected by ensuring that the meadows will continue to be mown in the future.
