A Contribution to Insect Studies in Ikh Nart Nature Reserve, Mongolia: Vespid Wasps (Hymenoptera, Vespidae)

Batchuluun Buyanjargal, Boldbaatar Jigmidmaa


Ikh Nart Nature Reserve remains poorly studied for invertebrates, especially for vespid wasps. A total of 14 vespid species belonging to seven genera of the subfamily Eumeninae were recorded from diff erent habitats (rocky outcrops, springs, tall vegetation habitats, shrub-lands and short grass steppes) in the nature reserve during three-year studies (2015-2017). These species represent 27 percent of the vespid fauna of the desert-steppe zone of Mongolia. We found the highest species richness in areas where water was available (near springs and wells), and the lowest richness in habitats with tall vegetation. Among the diff erent habitat types, vespid species composition was most similar (91% shared species) between rocky outcrops and spring habitats. Six vespid species range from Kazakhstan to Mongolian, and one species is sub-endemic to Mongolia. Availability of water sources and nesting sites were possibly the main factors infl uencing the distribution of vespid wasps. It is necessary to conduct comprehensive research into the insect community of Ikh Nart Nature Reserve.
