ABSTRACT. The social vespid wasps (Hymenoptera: Vespidae: Vespinae and Polistinae) was studied in Bhutan during 2014-2016. A total of fifteen species were collected and identified that all of them are reported as new Received: 17 February, 2017 records from Bhutan: Vespa vivax Smith, V. velutina variana van der Vecht, V. fumida van der Vecht, Dolichovespula lama (du Buysson), Vespula flaviceps Accepted: Smith, V. nursei Archer, V. vulgaris (Linnaeus), V. structor (Smith), Polistella 01 March, 2017 (Polistella) nigritarsus (Cameron), Parapolybia varia (Fabricius), P. nodosa van der Published: Vecht, Ropalidia artifex (de Saussure), R. stigma (Smith), R. ornaticeps (Cameron) 01 March, 2017 and R. rufoplagiata gravelyi (Dover & Rao).

The adults visit flowers sulcatus Smith, 1852, Polistes (Gyrostoma) searching for sugar-rich food materials as olivaceus (De Geer, 1773), Polistes they feed on it. They help in pollinating (Gyrostoma) rothneyi sikkimensis van der the flowers. Besides, adults also predate Vecht, 1968, Polistes (Polistella) santoshae Das & Gupta, 1989, Ropalidia fasciatus on insects to feed their developing larvae.

In this study, three Vespa, four been reported from Padong, Bhutan Vespula, one Dolichovespula, four Ropalidia, (Carpenter & Kojima, 1997; Das & Gupta, two Parapolybia and one Polistes species are 1989), Dolichovespula xanthicinta (Archer, reported as new records from Bhutan.
