April to September

Ynghylch

In April and May, queen shrill carder bees emerge from hibernation and build nests out of grass and plant fibres on the ground, or slightly underneath it. in each nest, the reigning queen rears her workers in wax cells, who subsequently rear the young on pollen and nectar. Each nest supports a small colony of workers and a queen. Workers are on the wing from May to late September and males from July to late September. The queens hibernate from October to April. Sadly, the shrill carder bee is now only found in a handful of locations in the UK, including large military ranges and unimproved pastures in Somerset, Gwent, Pembrokeshire, Glamorgan, and along the Thames corridor.
