Early-spring fauna of the moths (Lepidoptera, Metaheterocera) of Onokhoy town territory (Western Transbaikalie)

Fauna of Metaheterocera (Lepidoptera) of early-spring time (it is time from the first half of April to the media of May) of the Onokhoy town was considered. From 1996 to 2017 years in this place was found the nine Metaheterocera species from this time group. Some of them (Chloroclysta miata, Nycteola eremostola, Lithophane socia, Xylena vetusta) may be considered as autumn-early-spring species because their imago are overwinter. From early- spring group of species were excluded species with activity in the second half of May. But this species were included to the group of early-spring types in the Baikal strict nature reserve because they fly out there before. Early-spring fauna of Metaheterocera is unknown in most regions because there are almost no entomological researches in this time.
