This series shows a plasterer bee emerging from her burrow. These are solitary bees, meaning they each have their own nest site, unlike honey bees who all live together in great numbers in one large nest (such as a hive). However, plasterer bees form large aggregations and you can find hundreds of distinctive mounds with their entrance holes, close together on a site.

They are called plasterer bees because they use a type of polyester-like material to plaster the inside of their cells. This protects the developing egg from moisture. They are also unusual in that the females don't carry the pollen they collect on their bodies, but swallow it instead. They later regurgitate it along with nectar, in their nest cells and lay their eggs on top of this rather soupy mix, according to Stephen Marshall.
