The genus Hylaeus is a large diverse cosmopolitan group within the bee family Colletidae. The genus is also commonly known as the “yellow-faced bees”, although not all have yellow faces, some genus have white markings on their face.
With the common name of Masked Bee (Hylaeus sp), they get their name from the distinctive yellow or white markings on their face. Other addition to the “masked bees” name may define other features, such as the Red-headed Masked Bee (Hylaeus ruficeps).
The Hylaeus genus of bees occur on all continents except for Antarctica.
The pictured Hylaeus sp is very small, no more then 6 mm in overall length. The abdomen is a dark red-brown with similar colouration across the head. The thorax is black with yellow patches. It is thought to be Hylaeus ruficeps or Hylaeus ruficeps ruficeps.
There are approximately 173 species of the genu Hylaeus found in Australia, with 14 out of the 16 sub-genera of Hylaeus endemic to Australia. Research suggests that the genus Hylaeus originated from Australia, around 30 million years ago.1
