Natural history of some Siberian melitaeine butterfly species (Nymphalidae: Melitaeini) and their parasitoids

Abstract

We report observations on the larval gregarious behaviour, host plant use and parasitoids of six species of melitaeine butterfly in the Russian Republic of Buryatia. We observed post-diapause larvae in two habitats, steppe and taiga forest region. Five species were found in the steppe region: Euphydryas aurinia davidi, Melitaea cinxia, M. latonigena, M. didymoides and M. phoebe. Three species (M. cinxia, M. latonigena and M. didymoides) fed on the same host plant, Veronica incana (Plantaginaceae). Euphydryas aurinia larvae were found on Scabiosa comosa (Dipsacaceae) and M. phoebe larvae on Stemmacantha uniflora (Asteraceae). Three species were found in the taiga region (M. cinxia, M. latonigena and M. centralasiae), of which the first two fed on Veronica incana. Five species of hymenopteran parasitoids and three species of dipteran parasitoids were reared from the butterfly larvae of five species. © Entomologica Fennica. 22 October 2001.
