ABSTRACT. On the basis of literature data and collection materials, data on the distribution and phenology of migratory dragonfly Pantala flavescens near the northern limit of the range in Transbaikalia and Far East of Russia are summarized. P. flavescens live here only in the summer-autumn period. In May and June, they arrive from the southern parts of the range to its northern boundaries, where the summer “temperate” generation develops. The northernmost known place of the development of these dragonflies has been determined (Blagoveshchensk, 50°17'11" N, 127°30'52" E). In September, the descendants of immigrants supposedly migrate to the south to the original warm part of the range. It is assumed that this strategy is characteristic only to the part of individuals of population, and the majority of dragonflies arrive temporarily to the territory of the Far East of Russia and do not leave any progeny.
KEY WORDS: Pantala flavescens, distribution, phenology, development, migrations, Transbaikalia, Far East of Russia.
