ABSTRACT. Four migratory dragonfly species, Anax ephippiger, A. parthenope, Pantala flavescens and Sympetrum fonscolombii, arriving in Tajikistan for reproduction in spring 2019 from southernmost parts of the areal, were studied. In spring, populations of the most abundant and widespread immigrant species, Anax parthenope, presumably include immigrants from both southern and local residents. Ephemeral water ponds, mainly rice fields, are more preferable for oviposition of Pantala flavescens and Sympetrum fonscolombii, and probably typical of Anax ephippiger, but a different type water reservoir is necessary for A. parthenope and for a number of local eurytopic non-migrating dragonflies.
KEY WORDS: Odonata, Anax ephippiger, Anax parthenope, Pantala flavescens, Sympetrum fonscolombii, spring immigrations, Tajikistan.
