About Hylaeus nubilosus (Smith, 1853)
Hylaeus nubilosus (Smith, 1853) is a medium-sized masked bee, measuring 6 to 9 mm in body length. It has a conspicuous yellow thoracic patch located in the middle of its scutellum and metanotum. This bee is endemic to the eastern states of Australia, and has also been recorded at several suburban sites in the Perth region of southwestern Western Australia. Hylaeus nubilosus prefers to nest in abandoned nests left by mud-dauber wasps of the family Sphecidae, and potter wasps of the subfamily Eumeninae.
