The genus *Hylaeus* is nearly cosmopolitan, being found everywhere except for which single continent?
Answer
Antarctica
The yellow-faced bees, classified under the genus *Hylaeus*, exhibit remarkably wide geographical success, spanning numerous continents and diverse climates globally. This widespread distribution suggests high adaptability for the genus as a whole. Despite this global ubiquity, there is one extreme continent where members of this genus are entirely absent. That region, characterized by its severe cold and ice coverage, is Antarctica, confirming that even widely distributed genera have strict environmental limits to their colonization.
