Study sheds light on UK’s ‘overlooked’ bee species

CAMBRIDGE, U.K.–Findings from ARU project could help to protect solitary, ground-nesting bees
The UK’s first citizen science project focusing on solitary, ground-nesting bees has revealed that they nest in a far broader range of habitats than previously thought.
There are approximately 250 species of solitary bee in the UK, but far less is known about these important pollinators compared to honeybees or bumblebees.
Although some previous studies have examined their foraging activities, there has been little research into their nesting behaviour as their nests can be difficult to find. This is why academics from Anglia Ruskin University (ARU) called on the public to help.
Dr Stephanie Maher (now based at Trinity College Dublin) and Dr Thomas Ings of Anglia Ruskin University (ARU) led the solitary bee citizen science project and the results, which could help shape how land is managed to better protect ground-nesting bees, have been published in the journal Ecosphere.
The project asked the public to report active nesting sites of four different species that nest close together in aggregations: the tawny mining bee (Andrena fulva), the ashy mining bee (Andrena cineraria), the yellow legged furrow bee (Halictus rubicundus), and the ivy bee (Colletes hederae).
In total, almost 400 submissions were made to the site during 2017 and from the verifiable recordings it was found that the solitary bees studied were able to nest across a broad range of habits, although distinct preferences were found between species.
The recordings found that 82% of tawny mining bee nests were on flat ground and 68% were in at least partial shade. Meanwhile 74% of ivy bee nests were fully exposed to sunlight, and they were equally at home on flat or sloped ground.
