Helianthemum nummularium L. (Cistaceae) and Erodium cicutarium L., Geranium pratense L., Geranium sanquineum L., and Geranium pusilum L. (Geraniaceae) were mentioned as larval host plants from Poland so far, but no data about preimaginal stages of the species were known from south-eastern part of the country. From 2009 up to 2014 many new records of imagines of A. agestis were revealed in mountain and sub-mountain zones of Podkarpacie region, where A. agestis was known from few isolated localities. Additionally, during the observations carried out in 2012 in central and south Podkarpacie region, eggs and early instar caterpillars (L1 & L2) of the secondgeneration were found for the first time in nature on Geranium phaeum L. (Lipnik), and their occurrence on G. pratense L. was detected at the locality of Markowa. Interactions of caterpillars with ants were not recorded. In conclusion, A. agestis is in expansion in mountain and sub-mountain zones of Podkarpacie region (south-easternPoland) and Geranium phaeum L. is established as the new larval host plants of A. agestis from Poland.}, type={Text}, title={New data on Aricia agestis (Lepidoptera: Lycaenidae), its life history and occurrence in the Podkarpacie region of Poland}, URL={http://rcin.org.pl/miiz/Content/60555/PDF/WA058_80098_P256-T59_Frag-Faun-Nr1.pdf}, volume={59}, number={1}, journal={Fragmenta Faunistica}, publisher={Muzeum i Instytut Zoologii Polskiej Akademii Nauk}, keywords={expansion range, host plant, Geranium phaeum, life history, Polish Carpathian Foothills, south-eastern Poland}, }
