A new species of the genus Platycheirus Le Peletier et Serville, 1828 (Diptera, Syrphidae) is described from the Taimyr Peninsula (North of Krasnoyarsk Region). The new species belongs to the manicatus subgroup, being close to P. groenlandicus Curran, 1927, but differing by the narrower angle of approximation of the eyes (approximately equal 90 degrees) and the presence of short black setae on ...

Wildflower strips and biodiversity-friendly management are promoted as ways of enhancing biodiversity natural pest control in agroecosystems. Their efficacy for providing resources shelters enemies has been well studied, but little is known about how wildflower strip mediated by local field landscape composition. In this study, we explored the effects floral perennial flower on faba bean aphids...

Allograptaterraenovae sp. n. and Allograptanotiale sp. n. are described from Australia. Notes on the Australian species of Allograpta and an identification key to them are also given. The lectotype of Allograptajavana Wiedemann is designated, and the species Syrphuspallidus Bigot is synonymized under Allograptaaustralensis (Schiner).

Dasysyrphus Enderlein (Diptera: Syrphidae) has posed taxonomic challenges to researchers in the past, primarily due to their lack of interspecific diagnostic characters. In the present study, DNA data (mitochondrial cytochrome c oxidase sub-unit I—COI) were combined with morphology to help delimit species. This led to two species being resurrected from synonymy (D. laticaudus and D. pacificus) ...
