Abstract
The endemic large carpenter bee, Xylocopa darwini Cockerell, was the only known pollinator to the Galápagos Archipelago but as early as 1964 locals also spoke of the “dwarf bee of Floreana”. We report the presence of the wool carder bee, Anthidium vigintiduopunctatum Friese, on the island of Floreana and use a species distribution model to predict its distribution in the archipelago. We found that this species has the potential to invade almost one-third the surface area of the Galápagos Archipelago, primarily in low arid areas. Given that wool carder bees are uncommonly collected, we discuss whether this species is a previously undetected native bee or a recent adventive species to the Galápagos.
