First record of the Asiatic bee Megachile disjunctiformis in Europe.


Megachile disjunctiformis Cockerell 1911 (Hymenoptera Megachilidae) is recorded for the first time in Europe. After previous observations in 2011 and 2016 near Bologna, Italy, three specimens (one female and two males) were captured in three different locations of the Bologna area in 2017 and identified. The species is known from China, Japan, Taiwan, Hong Kong and Korea. In this paper a description of the specimens and comparison with other similar species are provided. Furthermore visited plants are indicated. The finding localities are relatively close to two important Bologna trading areas, suggesting that these may be the original sites of introduction in Italy. Little is known about this species and its biology in Italy will be subject of future investigations.
