“…The most likely route connecting the Eastern and Western Hemispheres seems to be via the central Atlantic Ocean from West Africa, where individuals would be supported by trade winds blowing towards northern South America and the Caribbean. This dispersal path has been demonstrated for two other migratory Odonata of African origin, Anax ephippiger (Burmeister, 1839) and Tramea basilaris (Pali sot de Beauvois, 1807) (Lambret et al, 2013;Hedlund et al, 2020;Meurgey & Poiron, 2012) as well as the desert locust Schistocerca gregaria (Forsskål, 1775) (Lovejoy et al, 2006). Seasonal winds may also assist the movement of swarms of P. flavescens as far away from the tropics as about 52°N in East Asia (Borisov, 2012;Cao et al, 2015), North America (May, 2013) and, recently, also in parts of Europe (Buczyński et al, 2014); in these high latitude regions they probably do not survive the winter (Borisov, 2012;Borisov & Malikova, 2019;May, 2013).…”
