A bumblebee lands on a lavender spike, hugs the flower, and buzzes so loudly you can hear it from a metre away. It is one of the most rewarding garden insects to watch, and you can identify the common species without catching them. The trick is to look at three things: the colour bands on the body, the colour of the tail, and the way the bee behaves. This guide covers the seven bumblebees you are most likely to meet in a British garden, from the giant buff-tailed queen in March to the ginger carder bee still working the asters in September.

Three clues: bands, tail and behaviour

Colour bands are the yellow, black, white or ginger patches on a bumblebee’s body. The tail is the fluffy tip of the abdomen, and it is often the quickest clue. Size matters too, but remember that queens are much larger than workers of the same species.

• Bands: count the yellow bands. One, two or three? Are they lemon-yellow or a deeper mustard?
• Tail: white, buff, red, orange or ginger? A clean white tail points to one group; a peachy tail suggests another.
• Size and shape: a huge bee in early spring is likely a queen. A small, round bee in midsummer may be a worker. A long face usually means a long tongue.
• Behaviour: some species nest underground, some in bird boxes, and some comb moss on the ground. Where you see the bee can be as useful as what it looks like.

The seven common garden bumblebees

1. Buff-tailed bumblebee

Large and unmistakable when you see a queen: black with two yellow bands and a buff or peach-coloured tail. Workers are smaller and their tails can look white, which causes most beginner confusion. Buff-tailed bumblebees nest underground, often in old mouse holes or under sheds. They love lavender, borage, clover and daisies, and queens appear very early in spring.

2. White-tailed bumblebee

Almost identical to the buff-tailed bumblebee, but the tail is bright white and the yellow bands are often a cleaner lemon. Queens are large and fly from early spring. They also nest underground. If the tail has any warm buff tinge, lean towards buff-tailed; if it is snowy white, white-tailed is likely.

3. Red-tailed bumblebee

Mostly black with a vivid red or orange tail. Queens are big and bold; workers are smaller versions. Males have yellow facial hair and often a yellow band on the thorax. They nest in holes in walls, under stones and in dry grass. In gardens they visit thistles, knapweed, lavender and daisies.

4. Early bumblebee

Small, fluffy and quick. Look for a yellow collar, often a second yellow band on the abdomen, and an orange-red tail. Queens emerge early and often nest in bird boxes or holes in trees. This is a common garden bee in spring, especially around fruit blossom and flowering currant.

5. Garden bumblebee

A long face and a long tongue make this species a specialist at deep flowers such as foxgloves, honeysuckle, snapdragons and comfrey. It is black with three yellow bands and a white tail. It nests underground or in bird boxes and is a familiar sight in British gardens through summer.

6. Common carder bee

Entirely ginger-brown and fluffy, with no clear colour bands. The tail is the same warm ginger, sometimes faded. Carder bees comb moss and grass together for their nest, often on the ground. They have a long tongue and visit lavender, sage, comfrey and runner beans.

7. Tree bumblebee

A relative newcomer that has spread quickly. It has a ginger-brown thorax, a black abdomen and a white tail. Tree bumblebees often nest in bird boxes, roof eaves and holes in trees. They appear early, can be very abundant, and males sometimes hover in a small cloud outside the nest.

Garden habits and timing

Bumblebees do not all follow the same calendar. Queens overwinter alone and emerge at different times, then start a nest and raise workers. By late summer, new queens and males appear. The new queens mate, feed up and find a place to sleep through winter.

• Early spring: large queens search for nest sites and nectar. Buff-tailed, white-tailed, early and tree bumblebees are often first.
• Midsummer: workers gather pollen and nectar. Carder, garden and red-tailed bumblebees are common now.
• Late summer: males patrol and new queens fatten up. You may see more bees on late flowers such as asters and sedum.
• Autumn: new queens seek sheltered spots to hibernate. Leave quiet corners undisturbed if you can.

How to identify a bumblebee step by step

1. Watch the tail first. White, buff, red or ginger?
2. Count the yellow bands. One, two or three? Note where they sit.
3. Check size. Is it a queen or a worker?
4. Look at the flower and the month. A long-tongued bee on a foxglove in July is a strong clue.
5. Take a photo if you can. A side view and a back view help enormously.
6. Compare with a good field guide or a local recording scheme. You will soon recognise the regulars.

You may also spot cuckoo bumblebees, which do not collect pollen and often have darker wings. They are fascinating, but they are not covered here. For beginners, the seven species above are the ones to learn first.

Make your garden a bumblebee café

Bumblebees need nectar and pollen from early spring to late autumn. Plant in generous clumps rather than single plants, because bees find larger patches more easily. Good choices include hellebore, mahonia and willow for early queens; lavender, comfrey, borage, salvia, thyme and marjoram in summer; and knapweed, thistle, asters and sedum for late workers and new queens.

Nest sites matter just as much. Leave a patch of long grass, a log pile or a dry bank undisturbed. A bird box with a small entrance can attract tree bumblebees. Avoid pesticides, and if you must use them, follow the label carefully and keep them away from flowers in bloom. A shallow dish of water with stones for landing helps on hot days.

Your first ten minutes of bumblebee watching

Choose a warm, still day and find a sunny patch of flowers. Sit close, stay still and pick one bee. Note its tail, its bands, its size and the plant it is visiting. Do this for ten minutes and you will learn more than from an hour of reading. Soon the buff-tailed queens, the tiny early bumblebees and the ginger carder bees will stop being anonymous. You do not need to handle them; watching is enough.
