wandering glider (Pantala flavescens)
Their arrival in the subtropics and tropics coincides with the Intertropical Convergence Zone. More evidence of their preference for moist winds, is that the dragonfly migrates to Southeast India's Tamil Nadu only after the second monsoon which is brings the rain to that region. In the rest of India, however, it arrives with the first rain-making monsoon. Observations suggest that they migrate from India to Africa across the Arabian Sea.
It is the highest-flying dragonfly, recorded at 6,200 m in the Himalayas. It was also first dragonfly species that settled on Bikini Atoll after the nuclear tests there. Furthermore, it is the only Odonata on Easter Island. These individuals seem to be a small gene pool, derived from the continental populations, which is slowly creating a new type by genetic drift. In colder areas like South Australia and Northern Canada, the species cannot overwinter and must therefore be replaced by new migrants each year.
