ABSTRACT
Pollination plays a critical role in sustaining much of the biodiversity on Earth and, as a result, plays an essential service in maintaining the integrity and resilience of most terrestrial ecosystems and the services that these ecosystems provide.1 There are around 150,000 flower-visiting pollinators, the majority of which are flies, butterflies, moths, bees, wasps and beetles as well as a small number of animal pollinators such as birds, bats and some non-flying mammals. One of the more common and most prolific pollinator groups is the bee, of which there are between 25,000 and 30,000 different species.2
