Abstract

Changes in Lepidoptera fauna (without micromoths) from Southern Primorye to the Amur River mouth is analyzed. The most significant change in south-to-north direction is recorded on the northern border of rich broad-leaved forests. This line is suggested to be considered as the north-eastern border of the Amur-Manchurian (Stenopean of Palaearchaearctic) choron. An additional barrier is recorded along the river Gur. In the opposite direction, the faunal change is gradual and insignificant. The territory to the north from this border, at the Amur River mouth, is inhabited by transitional fauna with a significant share of nemoral species. The main faunistic barriers for different phenological complexes (spring, summer and autumn) differ by their positions: for the summer complex the barrier goes along the rich broad-leaved forest border; for the spring complex – between Khabarovsk and Komsomolsk-on-Amur, for the autumn complex – between Southern Primorye and Komsomolsk-on-Amur. All these regularities were registered in all Lepidoptera groups studied.
