Diversity and ecology of hawk moths of the genus Hemaris (Lepidoptera, Sphingidae) of the Russian Far East

In this article, four species of the genus Hemaris (Lepidoptera, Sphingidae) are recognized from the Russian Far East: Hemaris ottonis (Rothschild and Jordan, 1903), Hemaris affinis (Bremer, 1861), Hemaris fuciformis (Linnaeus, 1758), and Hemaris radians (Walker, 1856). An identification key, redescriptions, distributions, and overviews of the ecology of Hemaris species in the Russian Far East are provided. The larval host plant of H. ottonis is recognized for the first time as Weigela praecox (Caprifoliaceae). The morphology and biology of preimaginal stages of H. ottonis have been studied for the first time. Larvae of this species are very different from other Hemaris species. The life cycle of H. radians is given for the first time, with its larval host plant in the southern part of Primorsky Krai determined to be Scabiosa lachnophylla (Dipsacaceae).
