Phengaris ‘rebeli’ Hirschke is a globally threatened obligatorily myrmecophilous and xerothermophilous butterfly. Caterpillars are initially endophytic and feed in flowerheads of Gentiana cruciata L. but they complete their development as social parasites of Myrmica Latr. ants. Relationships with hosts are specific and show geographical variation in Europe. Knowledge on them is vital for effective conservation. In Poland ‘P. rebeli’ was recorded from a dozen or so sites in the SE part of the country and from one locality in the Pieniny Mts. – a low calcareous mountain range on the Polish-Slovak border that constitutes a distinct geobotanical unit with specific climate and diversity of habitats. Present studies aimed to identify hostants of the butterfly in the Pieniny Mts.A total number of 30 Myrmica colonies were searched in 2008 near larval food plants bearing eggs of ‘P. rebeli’ in the previous season. We observed caterpillars and pupae of the butterfly exclusively in nests of M. schencki Em., i.e. 4 of 4 of them were infested. However, we did not find prematures of P. ‘rebeli’ with M. sabuleti Mein., M. rugulosa (Nyl.) and M. rubra (L.) which were also present in the turf. This makes the Pieniny population completely distinct from previously studied populations in SE Poland and similar to those known from Lithuania, France and Spain. It is probably related to the variation in chemical mimicry of P. ‘rebeli’ caterpillars. Our finding contributes to knowledge on the pattern of host-ant use of the butterfly in Europe and is also important for conservation on a local scale.

Examination of populations of M. schencki Viereck at sites in Italy showed that there appeared to be an Italian form characterised by workers having much wider frons than is normal for M. schencki. Morphometric comparison with M. schencki from all over its range showed that not only do the Italian female castes have a wider frons, their males also have a relatively longer scape that is less acutely angled at its base. These differences are consistently sufficient for the Italian form to be a species distinct from M. schencki. Comparison with other forms in the schencki-species group of Myrmica Latr. shows its workers, queens and males to be fully compatible with the type specimens of M. schencki var. obscura Finzi, which was considered as a junior synonym of M. schencki. Here we revive the name M. obscura from synonymy and raise it to species. Its distribution is discussed.

Unusual rubbish piles of Myrmica schencki Em. colonies nesting within territories of Formica polyctena Först. are described. The piles tightly surrounded M. schencki nest entrances and consisted mainly of remains of F. polyctena corpses (with a small addition of corpses of other local ant species) previously collected as food by M. schencki foragers in F. polyctena waste disposal zones. This observation shows that, under certain conditions, M. schencki can actually be a specialised myrmecophagous scavenger. The peculiar finding of M. schencki rubbish piles, in connection with other observations of using dead bodies and other remains by ants, suggests that such piles can play some role in interspecific relations in ants. This possibility is considered in the context of the competitive hierarchy of ant species.

Myrmica schencki Em. and M. rubra (L.), common Palaearctic ant species, collect fallen male Scots pine (Pinus sylvestris L.) inflorescence during the pine blossom time, take it to their nests and then gather it on rubbish piles close to nest-entrances. Dissection of M. schencki workers revealed the presence of numerous pollen grains in their crops and midguts proving at least periodical pollenivory of these ants. So far, only some Neotropical ants of the genus Cephalotes Latr. have been known to eat pollen.

The paper contains a taxonomie review of 13 species of the genus Myrmica Latr. occurring in Poland with information on their geographical ranges, distribution in Poland and biology. The following species are under discussion: M. rubra (L.), M. ruginodis Nyl., M. sulcinodis Nyl., M. lobicornis Nyl., M. rugulosa Nyl., M. gallienii Bondr., M. hellenica For., M. specioides Bondr., M. scabrinodis Nyl., M. sabuleti Mein., M. lonae Finzi, M. hirsuta Elmes arid M. schencki Viereck. A key for identifying them on the basis of workers and males is included.
