[Objectives]  The meadow moth, Loxostege sticticalis L. is a cosmopolitan pest inhabiting in the temperate zone between 36°N and 55°N. Clarifying the spatiotemporal dynamics of the meadow moth population in the whole of Eurasia is important to understand the outbreak mechanism of this species. [Methods]  Meadow moth infestations since 1900 were summarized by searching older Russian and Chinese literature and historical records. [Results]  There have been four periods with large outbreaks of meadow moths in Eurasia since the mid-1920 s; 1925-1936, 1948-1960,1969-1989 and 1995-2014. In three of these, meadow moths spread eastward, or westward, along the Eurasian Steppe, except for 1948-1960 when outbreaks were mainly limited to Northeast Asia. In addition, the meadow moth population had different outbreak cycles in different regions. In the European part of Russia, meadow moths have a cycle of about 10 years, except for an interval of more than 30 years from 1937 to 1968. In Northeast and North China, outbreaks have occurred about once every 20-years. Meadow moth outbreaks have been more frequent in Siberia, probably because this is located between the two main Eurasian breeding areas. Outbreaks have occurred irrespective of whether the meadow moth infestation spreads from west to east or from east to west. [Conclusion]  Plague-like outbreaks of the meadow moth have periodically occurred in Eurasia causing severe damage that has spread eastward or westward along the Eurasian Steppe. This suggests that outbreaks of the meadow moth in a specific region may be related not only to local environment factors, but also to their spreads in the continental scale.
