ResumoThe results from ten years of surveys and observations of overwintering nvmjtbalid butterilies in various tvpes of underground shelters in .SW'-W Bohemia, Czech Republic are presented.Dtiring these surveys, three species of nym|)halid butterilies were encountered; the most commonly observed species was Inachis io (Linneans), followed h\ Aglais urticae (I.inneaus).Nympha/is polychloros (I.inneaus) was encountered in the ten year period onlv twice, fhe tvpical overwintering sites for Inachis io were the ceilings of unlieated cellars of buildings, and the entrances of mining tunnels/galleries or natural caves.A special categorv of imdergrttund shelters in the study area was abandoned World War 2 militaiw bunkers.Inachis /ofrequently hibernates in aggregations of several individuals and Aglais urticae doea so less often.4'he lowest ambient air temperature measured in these tmderground shelters was -1.1° C. It is believed that these observations represent the longest continuous record of hibernating nvmphalid butterflies iu underground (or other) shelters in Czech Republic.
