description Amegilla dawsoni Overview

Amegilla dawsoni, commonly known as the Dawson's burrowing bee, is a large species of solitary bee native to Western Australia. First described by Tarlton Rayment in 1951, the species is known for building vast, dense nesting aggregations in hard claypans. Males exhibit extreme size dimorphism, with major males fighting fiercely to mate with females as they emerge from their burrows. These native pollinators are crucial to the local ecosystem, relying on nectar and pollen from the region's arid-adapted flora to provision their nests.

help Amegilla dawsoni FAQ

Where is the Dawson's burrowing bee native to?

Amegilla dawsoni is a large species of solitary bee native to the arid regions of Western Australia. They are particularly known to build vast, dense nesting aggregations in the hard claypans of the region.

How do male Dawson's burrowing bees behave?

Males of the species exhibit extreme size variation, with larger "major" males aggressively fighting each other to mate with emerging females. This intense competition makes them one of the most physically aggressive species of solitary bees.

How does the Dawson's burrowing bee build its nest?

The female bee digs deep, narrow tunnels into the incredibly hard claypan soil to create her nesting chamber. She then provisions the nest with nectar and pollen before laying a single egg inside and sealing it.

When was Amegilla dawsoni first scientifically described?

The species was first described by the Australian entomologist Tarlton Rayment in 1951. Since then, it has become a key subject for scientists studying solitary bee behavior and mating competition.
