Bumblebee colonies have for the most part finished, with a few new queens still stocking up on nectar before they hunker down for their winter diapause. The exception are the Buff-tailed bumblebees, which in many parts of the country can now be seen flying throughout the winter. In contrast, we will have to wait until next spring for a new generation of adult solitary bees to emerge. This year’s solitary bees have ended their life cycle save for a few remaining Ivy bees. Managed honeybees will forage on mild days. With so few bee species to choose from, it should at least be easier to identify the ones you do see!

Tips for IDing November bumblebees:

• Buff-tailed bumblebees (Bombus terrestris) – these large, fluffy, golden-striped bumblebees are active throughout the winter now in many parts of the UK, especially in cities even as far as Edinburgh and Dundee. The reason that late summer queens have a brood during winter now in many areas, rather than entering a winter diapause (hibernation-like state), is twofold: it is warm enough for the bees to fly in winter, and as importantly there is plenty for them to eat. Winter-flowering shrubs such a Mahonia and Viburnum tinus in our parks, gardens and municipal landscaping provides winter nectar and pollen. As a result, you’ll see queens, workers and males flying throughout the year. The queens are easily recognisable from their huge size (up to 24mm) and distinctive buff coloured bottom. You often hear their loud buzz before you see them. The workers are smaller (16mm) and have a white tail. Both of these castes are female. The 14mm males look similar to the workers. How you can tell them apart is from the brightly-coloured blobs of pollen, which only the females collect on their hind legs to take back to the nest. In more rural areas of northern England and Scotland, where the Buff-tailed bumblebees aren’t yet active over winter, you may still see a queen Buff-tailed bumblebee at this time of year stocking up on nectar and looking for a dry, secure place to spend her winter diapause, from which she will emerge in early spring.
• Common carder bees (Bombus pascuorum) – if you see a 15mm fluffy brown bee on flowering salvias or Fuchsia at this time of year, chances are they will be the new queens having a final nectar feast before bedding down somewhere snug for the winter months, such as a pile of old leaves, long grass, or under the garden shed.
• Tree bumblebee (Bombus hypnorum) – they have a gingery thorax like a Common carder bees, but the wihite bottom tells them apart.If you’re very lucky at this time of year you may see a queen out foraging for nectar before she hunkers down for the winter. These bees have spread across the British isles since they arrived from the continent in Wiltshire in 2001. Nowadays they seem more common in cooler parts of the UK. I’ve not seen one in my London garden for a decade now. If you put up a bird box for Blue tits in your garden, the tree bumblebees may make a nest in it after the chicks have fledged next spring.

How to ID November solitary bees:

• Ivy bees (Colletes hederae) –there’s a very slim chance you may see an Ivy bee early this month if ivy is still flowering where you live. But hurry, their short life cycle is nearly over. Once the adult female bees have laid all their eggs, and provisioned each one with pollen from the ivy flowers, their six to eight week life cycle is complete. To spot an Ivy bee, look for an insect with a fluffy ginger pile on top of its thorax (though it may be a duller brown by now) feeding on the last of the tiny, white ivy flowers. It’s the fluffy thorax that sets the 13mm Ivy bee apart from honey bees and hoverflies (See our Is it a bee or a hoverfly? guide.)

How to ID honey bees:

Western honey bees (Apis millefera) – we’ve included these managed bees this month because you are likely to see them foraging for nectar on late-flowering blooms, such as Geranium ‘Rozanne’ , Tickseed, Fuschia and Salvia – often nectar robbing (making a hole in the base of a deep flower to get the nectar because their short proboscis (tongue) can’t reach inside the flower. This means the flower doesn’t get pollinated). The honeybees take the nectar back to their hive to turn into the last stores of honey, which is their winter food. They may also be foraging on the last ivy flowers. They are around 10mm long with a slim, tapered gold and brown stripy body. They can be easily confused with other stripy insects, such as Ivy bees and the Marmalade hoverfly.

Bee mimic

Marmalade Hoverfly (Episyrphus balteatus) – is one of our most common hoverflies. It gets its common name from its thick orange markings which make it look like a stinging insect (which it isn’t) in the hope that this will deter potential predetors. The way to tell it apart from a bee is its big eyes, spindly legs which do not have pollen baskets, and it only has two wings (not four like a bee). It is also less hairy. It’s active throughout much of the winter when most bees aren’t flying . Hoverflies are among our most important pollinators. Like wasps, they also eat aphids so play an important role in pest control. More details here.

How to help bees in November:

1. Cosmos, Penstemon, Fuchsia, salvias, dahlias, tickseed and Geranium ‘Rozanne’ are all still flowering for late-flying bees, along with the shrub Fatsia japonica, so try to have some in your garden or in pots or planters.
2. Since most bee species don’t fly in the colder months, now’s the time to think ahead to next spring when a new generation of bees start emerging. Make you garden, roof terrace, patio or other outside space a smorgasbord of bee-friendly spring bulbs. If you only do one thing, plant those crocus bulbs you’ve been meaning to before the ground gets too hard. Plant them under trees, in lawns and hanging baskets, and pots, as well as flower beds. They will give the early flying bumblebee queens food to fuel their flight. Here are the best spring bulbs for bees.
3. For bee-friendly November window boxes, Cosmos and Mexican fleabane (Erigeron karvinskianus), are still blooming. I’ve just brought some magnificent magenta-coloured Cyclamen to brighten up my window box for autumn and feed passing bees and I have added crocus bulbs for a colourful display in early spring that will feed the bees.
4. The Strawberry tree (Arbutus unedo) feeds bees in November and it’s nectar and pollen contains medicinal properties for bumblebees, so try to grow one in your garden or a even a large pot. If you’d like a spring or summer flowering tree instead, now is the perfect month to decide which tree you could add to your garden to provide bee food next year. If you order it now, you can plant a tree, while trees are dormant during winter. Also, speak to your council tree officer about how they could be planting more bee-friendly trees in local streets and parks. Trees can provide an abundant source of food at times of year when bees may be going hungry like early spring and late summer. For advice on which tree to plant see our Trees for Bees guide. Some bee-friendly trees grow very well in pots, including small fruit trees such as crab apples. My favourite to feed the Red mason bees is Malus sylvestris ‘Evereste’.
5. If you live in a milder part of the UK, it’s worth planting winter-flowers shrubs, such as Mahonia, Verburnum tinus and Sarcococca, and perennials, such a Hellebores, to feed Buff-tailed bumblebees who fly all year round. More information on flowers here and shrubs here.
6. Have you ever thought of growing a wildlife-friendly hedge? Well this month is the time to get planning. Hawthorn, Blackthorn, Field Maple, Beech, Hornbeam, Purging buckthorn and Dog rose are some of plants that this RHS video suggests. It all really depends on what size garden you have, how prickly you want your hedge and how much you want it to flower for pollinators. We have a small Cotoneaster hedge in our small, urban front garden which mitigates pollution, has white flowers that feed bees in the summer, and berries for the blackbirds in winter. Even privet hedges are good for pollinators if they are allowed to flower. Bare-root hedges can be planted from late autumn into winter.
7. Divide bee-friendly perennials that have become overcrowded. Find another place for them in the garden or give them away to friends and neighbours to make their gardens more bee-friendly.
8. Seeds to grow under glass this month including wild cornflower, cowslip, poppies and Pink Hawk’s Beard (Crepis rubra) – a new hardy annual I’ve just come across which looks a bit like a pink dandelion . Yellow rattle can be grown outdoors and is useful if you are trying to convert part of your lawn into a wild flower meadow as it supresses the grasses and will allow the wild flowers to grow.
9. It’s tempting to give your garden a thorough tidy at this time of year after the autumn leaves have fallen. But it’s best to leave your garden a bit messy: piles of leaves and bits of old, rotting wood as queen bumblebees and other insects may find them perfect winter habitat. And there could be solitary bee cocoons in hollow plant stems, so leave them too.
10. Clean out your bee hotels and bee boxes for solitary bees and store the bee cocoons in a dry, cool place over winter. Read here for more information on bee hotel winter management.
11. If you see a motionless bumblebee at this time of year, either try and move here to a flower when she can suck up some nectar to give her energy, or you could give her a sugar/water drink, but NEVER give her honey. It has bacteria that is bad for bumblebees.

There will be plenty more jobs we can do over the winter months to help bees thrive next spring. So, look out for future posts.
