GWCT Species of the Month: Red-Tailed Mason Bee
The majority of our 250 bee species are what we call solitary bees, and these vitally important insects are split into distinct groups such as mining bees, cuckoo bees, leaf-cutter bees and mason bees.
The latter group, the mason bees, are often observed buzzing in a cloud around brick and stone walls and buildings.
