A. petalura taiyal is a genuine Taiwanese mountain dweller, found only at elevations above 1500 meters. Its close cousins, the other members of the genus Aeshna, are distributed across the temperate regions of North America and Europe, much further north than Taiwan. The ancestors of Taiwan's A. petalura taiyal moved here from the Himalayas in the ice ages.
