If you’ve still not seen an Ivy bee, get out this month while it’s still warm and dry in many parts of the UK and stand patiently by a buzzing ivy bush in the autumnal sunshine. This is where you’re likely to see them feeding on the tiny, white, pin cushion-like flowers for nectar and pollen, alongside slightly bigger honeybees that they can easily be confused with. Just to make it harder, they will be joined by heaps of stripy hoverflies. The photos above and the ID tips below are designed to help you tell a ivy bee and honeybee apart. And our Is it a bee or a hoverfly? guide should help distinguish both from their hoverfly mimics.

Also observe bees on later flowering blooms, such as Salvias, Michaelmas daisies, Fuchsia, Helianthus ‘Lemon Queen’, Cosmos and Penstemon. Some will be the longer-tongued Common carder bees whose ginger tufts will have probably faded to straw. Small workers and larger Queens will be flying, along with Red-tailed bumblebee queens, and ubiquitous Buff-tailed bumblebees. And tiny furrow bees may still be seen.

My best advice to you this month is the same as I give every October; make the most of any mild, bright autumnal days to get out and spot many of the last bees of 2022.

Tips for IDing October bumblebees:

• Common carder bees (Bombus pascuorum) – the workers will often sport a faded ginger/brown thorax that looks more straw-coloured at this time of year. They will often be seen foraging on Helianthus ‘Lemon Queen’, Michaelmas daisies and Salvia ‘hot lips’ in my garden, alongside new, more vibrant looking queens and males stocking up on nectar before the winter. The queens are the largest (15mm) and the workers the smallest (11mm). Despite its English name, which derives from its behaviour of teasing out (carder is the old fashioned word for teasing out) bits of moss to cover its nest, it is a social bumblebee, hence its Latin Bombus tag.
• Red-tailed bumblebees (Bombus lapidarius) – one of my main disappointments of bee spotting again this year was how few of these gorgeous velvety black bees with their fiery red bottoms I’ve seen in my garden or local parks in east London. However, I did spot some of the pretty, yellow-faced males so there must be queens around. Anyway, be on the look out in these last few weeks for the new generation of large queens (17mm) who will now be mated and will be feeding on nectar to build up their fat reserves to see them through their dormant state during winter.
• Buff-tailed bumblebees (Bombus terrestris) – these white bottomed bumblebees with golden stripes are so successful that if you live in the south of the UK you are likely to see this species flying all year. This month, the huge queens (18mm) may be supping on ivy nectar alongside the other bees. In the south, they will be looking for a nest to produce a brood that lives throughout the winter. Further north, they are more likely stocking up on nectar before their dormant period and will appear early next spring to nest.

How to ID October solitary bees:

Ivy bee (Colletes hederae) – If there is one thing you should do before the end of the bee spotting season, it’s to try and see an ivy bee. Why? Here are ten reasons why ivy mining bees are so special:

1. They are the last solitary bee to emerge in the year.
2. They were only described as a separate species in 1993 in Germany. According to bee expert, Ted Benton, the lateness of this discovery may in part be explained by their similarity to two other late-flying close relatives: Heather bees (Colletes succinctus) and Sea Aster bees (Colletes halophilus).
3. They were first discovered in England just 20 years ago, in an ivy bush in Dorset in 2001.
4. There is a real thrill when you see one for the first time, because it means you have learned to distinguish its features (gingery pile on its thorax and segmented shiny bands on its abdomen) from the honeybee which is a bit bigger.
5. They only fly for around six weeks, when the ivy is flowering, so they seem more special than bees that fly all summer.
6. If you see one north of Shropshire, Staffordshire, Norfolk or south Wales you can contribute to a mapping project to show their spread across Britain.
7. They nest in huge aggregations of thousands of bees, making burrows in loose soil and sandy banks. It’s an amazing sight watching them emerge in late August/early September. I’ve never seen it, but I hope to create a sand bank somewhere that may become a nesting site. This video gives a flavour.
8. Their symbiotic relationship with ivy – emerging to feed on its nectar and pollen and pollinating it at the same time – really demonstrates the connection between bees and flowering plants. This relationship has evolved over 60 million years.
9. Watching them at work helps to connect us with nature on our doorstep. We don’t need to visit the ‘countryside’, or to far flung places, to see nature in action.
10. They are also called plasterer bees, because like all bees with the Latin name Colletes, they line the nests they create in their burrows with a cellophane-like waterproof and fungus-resistant substance that they secret. Isn’t that amazing!

Common furrow bee (Lasioglossum calceatum) – these small black elongated shiny bees have been flying all summer. I have to admit I’m still not confident about IDing them. I think it’s the fact they are small and black, whereas I still expect my bees to be more colourful and fluffy. But I am getting better. My rule of thumb is that if it’s a small black insect with a long body on a flower late in the summer or in autumn, chances are it will be this bee. I know the yellow legs in the photo above, should help, and there are some band markings on the body, but I find these hard to see when it’s only 5.5mm.

How to help bees in October:

1. There are still a few things flowering in the garden this month: Helianthus ‘Lemon Queen’, Michaelmas daisies and annual Cosmos grown from seed for short tongued or medium tongued bees; Penstemon, Fuchsia, Salvia ‘hot lips’ and other salvias for long-tongues bees. The shrubby blue Caryopteris x clandonensis (Bluebeard) and red Perscicaria are both visited by bees, and of course, Geranium Rozanne is still flowering. But flowering ivy is by far the most valuable nectar and pollen source at this time of year, so if you have any mature, flowering ivy don’t prune it until after it’s flowered.
2. For bee-friendly October window boxes, try Cosmos, Mexican fleabane (Erigeron karvinskianus), and Cyclamen.
3. Think about which tree you could add to your garden to provide bee food, or speak to your council tree officer about planting more bee-friendly trees in streets and parks. It’s best to plant trees during the winter when they are dormant.
4. If you only do one thing for bees this month, plant as many crocus bulbs as you can in window boxes, pots, hanging baskets, flower beds and lawns, as they will provide much-need early pollen and nectar for bumblebee queens when they start flying next spring.
5. October is a good time to divide 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.
6. If planting conditions are still good this month (not too cold and wet), it’s not too late to plant wallflowers. There are also some seeds that can be grown under glass this month including wild cornflower and cowslip. 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.
7. Leave parts of the garden untidy as queen bumblebees may have found a nook or cranny to spend the winter and don’t wish to be disturbed.
8. Clean out your bee hotels and store the bee cocoons in a dry, cool place over winter. Read here for more information.

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 each month.
