2021Azores - Europa - Endangered National Wildlife - First Day Cover

The Azores noctule (Nyctalus azoreum) is the only mammal that is endemic to the Azores archipelago. It is found in forests, where it feeds mainly on lepidopterans (such as moths and butterflies) and dipterans (such as mosquitoes), thereby helping to control insect pests. Unlike most bats, this animal often hunts during the day, probably due to the paucity of diurnal birds of prey.
