DAWSON'S BURROWING BEES (Amegilla dawsoni)
Some arid mud flats in central-western Western Australia are dotted with thousands of little mounds of clay. These are the nest entrances of the fascinating Dawson's Burrowing Bees. The crowded lives of these bold native bees have attracted international scientific interest.

New adults emerge from the nests in late winter or early spring. Competition for the favours of the new females is incredibly fierce and violent battles ensue. David Attenborough captured spectacular footage of the Dawson's Burrowing Bees for the BBC series LIFE and scientific studies by Dress Terry Houston, John Adcock and Leigh Simmons have revealed intimate details of the lives of these amazing bees.

The Dawson's Burrowing Bees, Amegilla dawsoni, are up to 20 mm long, with yellow face markings and a smooth red-brown abdomen. Females have dense white fur on their thorax while males have pale tan coloured fur. They belong to the family Apidae.
The following fabulous photos by Linda Rogan show a female bee emerging from her burrow, and two males competing for the attentions of an emerging female.
