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.
How to identify
The shrill carder bee is a small bumble bee. It has distinctive markings: it is grey-green in colour, with a single black band across the thorax, two dark bands on the abdomen, and a pale orange tip to the abdomen.
Did you know?
The shrill carder bee gets its name from the 'shrill' buzz that it makes, which is higher in pitch than that of other bees. The queens tend to produce a higher-pitched buzz than the males and workers.
How people can help
The Wildlife Trusts work closely with farmers, landowners and planners to ensure that our wildlife is protected and to promote wildlife-friendly practices. By working together, we can create Living Landscapes: networks of habitats stretching across town and country that allow wildlife to move about freely and people to enjoy the benefits of nature. Support this greener vision for the future by joining your local Wildlife Trust.
