What are blue-banded bees?

Blue-banded bees are native Australian bees best known for the bright, metallic blue stripes across their dark abdomen. The most commonly recognised species is the common blue-banded bee (Amegilla cingulata), although several Amegilla species can look very similar, so careful identification is sometimes needed.

Unlike honey bees, blue-banded bees are solitary. That means there is no big hive with a queen and workers. Instead, each female makes and provisions her own nest, and adults spend much of their time darting quickly between flowers to drink nectar and collect pollen.

Blue-banded bees travel through gardens and bushland looking for nectar and pollen.

Where do blue-banded bees live?

Blue-banded bees are found widely across mainland Australia and can be common in bushland, parks and gardens, especially where lots of flowers bloom through the year. They often do well in cities and suburbs because gardens can provide nectar and pollen across different seasons.

You might spot them in sunny, sheltered places where there are plenty of flowering plants nearby and places to nest in soft ground or rock. Because they move very fast, the easiest time to notice them is when they hover and zip between flowers, sometimes pausing just long enough to drink nectar.   Blue-banded bee clinging to a plant stem while resting.

What do blue-banded bees eat?

Adult blue-banded bees feed mainly on nectar for energy. Female bees also collect pollen, which is protein-rich and used to feed their young. You may see pollen stuck to their hairy legs or body as they move between flowers.

Because different plants flower at different times, a garden or bushland with a variety of flowering species can support blue-banded bees for longer parts of the year. This matters because adult bees must regularly refuel, and females need enough pollen and nectar to supply each nest chamber for their larvae.

What is the life cycle of a blue-banded bee?

Blue-banded bees don’t live in hives. A female builds a nest tunnel and creates separate rooms (cells) where she places an egg and a food supply made from nectar and pollen. The larva grows in that cell, using the stored food, before eventually emerging as an adult bee.

They often nest in soft sandstone or suitable soil and clay banks, and you may also hear of them using old mortar or crumbly material in sheltered places where digging is possible. Sometimes many nests occur in the same area because the habitat is good, even though each nest belongs to a different female.

How do blue-banded bees help plants?

Some flowers keep their pollen tucked away so it won’t fall out easily. Female blue-banded bees can solve this by buzz pollination: they grip the flower and rapidly vibrate their flight muscles, which shakes pollen loose so it can be collected.

Buzz pollination is especially useful for certain native plants and also for some food crops. It’s one reason blue-banded bees are often described as valuable pollinators—because the way they collect pollen can help flowers set seed or fruit more successfully.

Blue-banded bees use buzz pollination to help pollinate Australian native plants.

How can you help blue-banded bees?

You can support blue-banded bees by making your school or home garden a place where they can find food and shelter across the year. Planting a mix of flowering plants, especially local native species helps provide nectar and pollen in different seasons, which is important because bees need frequent food top-ups to stay active.

Blue-banded bees also need safe places to nest. Leaving a small sunny patch of firm soil, or a sheltered, undisturbed bank of suitable ground, can make nesting easier for solitary bees. Where possible, reducing or avoiding pesticides and herbicides also helps, because chemicals can harm bees directly or remove the flowering plants they rely on.

Gardens full of native plants provide food and resting places for blue-banded bees.
