Behaviour
The St. Lucia Basker is far more aerial than other Urothemis species and spends less time perched at the waters edge. It is most often seen on and around trees and bushes, with an abundance of long grass and water nearby. Perches conspicuously on top of trees, bushes and reeds etc. The flight is fast and powerful. It’s movements and life history are not yet fully understood.
Status and Conservation
Urothemis luciana is an uncommon to rare species with an erratic occurence. This species is not present at the same sites every year and appears to vanish during prolonged dry years, only to re-appear again after good rains. It is listed as Near Threatened in the IUCN Red List of Threatened Species. A significant portion of its South African range is protected within the iSimangaliso Wetland Park. The St. Lucia Basker is not known to occur at artificial habitats and is sensitive to habitat degredation.
Distribution
Urothemis luciana is endemic to north-eastern KwaZulu-Natal and southern Mozambique. It occurs as far South as Richards Bay.
