Buff-tailed bumblebee worker Honeybee with pollen on her back legs
Tips for IDing December bumblebees:
It’s not that you won’t see bees this month, but only two species fly in the winter. And only on mild, dry days, or when it’s bright and sunny (even sometimes when there is snow on the ground!)
Given there are only two winter fliers, bee identification is a lot less interesting than in spring and summer, but it is much easier. You are either observing a wild, Buff-tailed bumblebee or a managed honeybee, and in some parts of the UK it will only be the latter as the Buff-tailed bumblebees queens are hibernating, and not producing any workers.
- Buff-tailed bumblebees (Bombus terrestris) – until fairly recently these fluffy, golden-striped bumblebees hibernated like all other 23 bumblebee species in the UK. But in the late 1990s, they where observed foraging in various sites over winter. It’s believed that some summer queens set up nests in October (instead of hibernating until spring) and produce workers in November to take advantage of milder winters and the abundance of food provided by winter-flowering heathers, honeysuckles and especially widely-planted Mahonia. This tough shrub has bright yellow flowers that cheer up many an amenity shrubbery, car park, and city garden and park at this time of year, and produce copious amounts of nectar and pollen. You’re most likely see the workers foraging on it between now and February, especially if you live in a city in the south of England. They will collect blobs of its orange pollen in the baskets on their hind legs to take back to the nest to feed the brood.
How to ID honey bees:
Western honey bees (Apis millefera) – the managed honeybee colony stays alive at this time of year by keeping warm in their hive and eating the honey which they spend all summer making and storing to eat in the winter. On milder, sunny days or even cold, bright days when the sun has warmed up the hive, some worker bees will leave the colony to forage for winter-flowering shrubs near by, or just to go to the toilet (they don’t do this in the hive). That’s when you may see them. They are so much slimmer and smoother than bumblebees that there is no chance of confusing the two.
How to help bees in December:
- Plant a tree in your garden between now and February to feed bees in the future, or sponsor a street tree, or join a local tree planting group to plant trees in parks and community orchards. Some trees are better for bees than others, because they produce more nectar and pollen, or they supply it early in the spring, or in late autumn when little else is flowering. What bees really need are trees that blossom sequentially producing a bee banquet throughout the year. Check the Urban Bees’ Trees for Bees guide. If you plant a Himalayan cherry (Prunus rufa) or a Tibetan cherry (Prunus serrula) you’ll not only have great blossom for bees in spring (as long as you plant single flowered varieties, not double-headed ones), but also fantastic rich coppery, peeling bark in the winter.
- Plant a holly tree/bush – this will not only give you bright red berries to brighten up the garden at this time of year and feed birds, it will also produce small white flowers for bees in early summer. Note: Only female trees form fruit and they need to be planted near to a male for the bees to transfer the pollen from the male to the female to fertilise them. However the male holly could be in a neighbour’s garden. For a sure bet for berries, try self-fertile ‘J C van Tol’ which also attracts bees to its flowers.
- Underplant your tree with Christmas rose (Helleborus niger) whose large, bowl-shaped flowers are borne in loose clusters in late winter and spring, and Elephant’s ears (Bergenia), Lungwort (Pulmonaria) to attract early flying bees next spring.
- Leave your garden unkept so as not to disturb bumblebee queens who may be hibernating in piles of old leaves, long grasses or under a shed.
- It’s not too late to undertake bee hotel winter maintenance. Follow our simple step by step guide to care for these solitary bees over winter. Watch out for other insects hibernating in any empty tubes. I found queen wasps and spiders!
- Offer a lethargic or exhausted Buff-tailed bumblebee an emergency energy drink of sugary water. At this time of year they can get cold and exhausted very quickly after leaving the nest if they don’t quickly find nectar from a flower. A mixture of two tablespoons of white sugar to one tablespoon of water should revive them, but it may take them a while to find enough energy to suck up the liquid from the spoon or saucer you provide. Be patient. One way to ensure you are always prepared to revive a bee is by carrying a Bee Revival Kit with you at all times. It’s a vial filled with an ambrosia syrup that attaches to a key ring.
- An alternative is to pick a bee up and take her to a flowering bush, such as Mahonia, full of nectar-rich flowers if there is one nearby. But remember, bumblebees can sting if they feel threatened so pick her up on a leaf, or in a container.
- Never feed a bee honey. It sounds counterintuitive, but the bacterial spores of a disease that affects bee larvae can be found in honey and this brood disease is highly contagious.
