Western Australian Native Bee Species and Honey Bees – What’s the Difference?
Australian Native Bees vs Honey Bees: Understanding Western Australia’s Pollinators
The Australian native bee is one of the most vital yet often overlooked contributors to the health of our environment. Across Australia, there are over 2000 species of native bees, and Western Australia is home to more than 800 of these fascinating creatures. These bees play a crucial role in pollination, which supports not only our natural ecosystems but also our agriculture and food production.
Unlike the honey bee, which is commonly associated with hives and honey production, the Australian native bee is typically solitary and thrives in a variety of habitats. From WA’s diverse forests to its coastal regions, these bees are busy pollinating native wildflowers, fruit trees, and crops, ensuring the ongoing vitality of our flora and fauna.
Australia is home to around 2,000 species of native bees, each playing a vital role in pollination and biodiversity. Unlike the introduced European honey bee, most native bees are solitary, meaning they do not form large colonies or produce honey in significant amounts. However, a few species, like stingless bees (Tetragonula and Austroplebeia), do live in small social colonies.
Key Differences Between Native Bees and Honey Bees
Australian native bees differ from honey bees in several ways:
- Social structure – Most native bees are solitary, while honey bees live in large, highly organised colonies.
- Size and appearance – Native bees range from tiny 2mm species to larger 24mm bees, often with striking colours and patterns.
- Nesting habits – Many native bees build nests in the ground, hollow stems, or crevices, whereas honey bees create hives.
- Stinging ability – Most native bees are harmless, with stingless bee species being completely incapable of stinging.

The Unique Ecology of Western Australia’s Native Bees
Western Australia’s native bees are essential to the health of local ecosystems, supporting biodiversity and plant reproduction. Their presence in gardens, bushland, and farms ensures the pollination of native wildflowers, fruits, and crops, making them invaluable to both natural and agricultural landscapes.
The Benefits of The Australian Native Bee in Our Gardens and Ecosystems
Having native bees in gardens and natural spaces provides several advantages:
- Increased pollination – Many native plants rely on these bees for reproduction, ensuring healthy plant populations.
- Support for local wildlife – By pollinating native flora, bees contribute to habitats that sustain birds, insects, and other wildlife.
- Sustainable gardening – Encouraging native bees can lead to stronger, more resilient gardens without the need for chemical fertilisers.
Adaptability to WA’s Diverse Climates
Western Australia’s landscapes range from lush forests in the southwest to dry, arid deserts in the interior. Native bees have evolved to thrive in these varied environments:
- In rainforests and coastal areas, species like Reed Bees nest in plant stems and hollow reeds.
- In dry, inland regions, ground-nesting bees, such as Blue-banded Bees, create burrows in sandy soil, where they can withstand extreme heat.
- In urban areas, native bees adapt to backyard gardens, making use of logs, crevices, and even bee hotels.
Diverse Nesting Habits
Unlike European honey bees, which form large hives, most native bees nest independently. Their nesting habits vary based on species:
- Underground burrows – Many native bees, including Blue-banded Bees, dig tunnels in sandy or clay-rich soils.
- Tree hollows and wood crevices – Certain bees, like Resin Bees, seek shelter in cracks and cavities within trees.
- Plant stems and reeds – Reed Bees and Masked Bees create nests inside hollow plant stems, making them important pollinators in wetland areas.
By providing suitable habitats and planting native flora, Western Australians can help protect these vital pollinators and ensure the continued health of local ecosystems.
The Symbiotic Relationship: How Honey Bees Support Native Bees
Although European honey bees (Apis mellifera) are not native to Australia, they play a valuable role in pollination alongside native bees. Rather than replacing native species, honey bees complement their efforts, particularly in agricultural settings, creating a mutually beneficial relationship.
How Honey Bees and Native Bees Work Together
While honey bees are efficient generalist pollinators, native bees often specialise in pollinating certain plants that honey bees cannot access as effectively. This complementary relationship benefits both ecosystems and agriculture:
- Honey bees pollinate large-scale crops – Their ability to pollinate vast areas of fruits, nuts, and vegetables ensures consistent food production.
- Native bees pollinate unique native plants – Many Australian wildflowers rely on native bee species, such as Blue-banded Bees, for buzz pollination.
- Increased biodiversity – The combined efforts of honey bees and native bees lead to stronger plant populations and more resilient ecosystems.
The Mutual Benefit: Agriculture and Native Bee Food Sources
The presence of honey bees in agricultural settings helps boost crop yields, leading to increased flowering and fruiting in surrounding landscapes. This, in turn, provides more food sources for native bees, ensuring their survival in both natural and urban environments. For example:
- The pollination of fruit and nut trees by honey bees increases nectar availability, which also benefits native pollinators.
- The success of wildflower industries (such as WA’s wildflower honey production) depends on both honey bees and native bees contributing to plant reproduction.
Coexisting in Harmony
Although competition for floral resources can occur, honey bees and native bees generally occupy different ecological niches, allowing them to thrive together. Conservation efforts, such as planting diverse native flora and providing nesting sites, can help maintain this balance. By recognising the distinct but complementary roles of both bee types, we can support a healthier, more productive environment for all pollinators.
The Importance of Pollination for Honey Production
Western Australia’s honey industry thrives on the pollination efforts of honey bees (Apis mellifera), which play a crucial role in producing high-quality, locally sourced honey. By foraging on a wide variety of native and agricultural plants, honey bees help ensure the reproduction of flowering species while also collecting nectar to create WA’s renowned honey varieties.
Honey Bees and WA’s Honey Industry
The vast, unspoiled landscapes of WA provide honey bees with access to some of the purest floral sources in the world. Their pollination efforts directly impact:
- The production of premium monofloral honeys – Varieties such as Jarrah honey, Marri (Red Gum) honey, and Karri honey depend on honey bees to pollinate these native eucalypts.
- Sustained honey production – Healthy bee populations ensure ongoing nectar availability, supporting WA’s commercial beekeepers.
- Crop pollination for honey flow – In addition to native flora, honey bees pollinate fruit and nut orchards, boosting overall yields and nectar supplies.
Australian Native Bees and Unique Honey Flavour Profiles
While honey bees are the primary producers of commercial honey, native bees also contribute to the complexity of Australian honey. By pollinating native wildflowers that honey bees may overlook, native bees help enhance the biodiversity of nectar sources, which can influence the flavour of honey.
- Native wildflowers such as banksias, grevilleas, and melaleucas benefit from native bee pollination, creating richer floral diversity.
- This results in nuanced honey flavours that reflect the unique ecosystems of WA.
By supporting both honey bees and native pollinators, WA’s honey industry not only ensures sustainable honey production but also preserves the natural landscapes that make Western Australian honey some of the finest in the world.
The Threats Facing Native Bees in Western Australia
Despite their vital role in pollination and ecosystem health, native bee populations in WA face increasing threats from environmental changes and human activities. Protecting these important pollinators is essential for maintaining biodiversity and ensuring the health of both native flora and agricultural crops.
Environmental Threats to Native Bees
Several key factors are contributing to the decline of native bee populations in WA:
- Habitat loss – Urban expansion, land clearing for agriculture, and deforestation reduce the availability of nesting sites and food sources for native bees.
- Pesticides and chemicals – The use of insecticides and herbicides can be toxic to bees, either killing them directly or reducing their access to safe foraging areas.
- Climate change – Rising temperatures, altered rainfall patterns, and extreme weather events impact the flowering cycles of plants that native bees depend on for nectar and pollen.
The Impact of Invasive Species
Non-native species also pose a threat to WA’s native bees by competing for food and nesting sites:
- Feral honey bees – Escaped European honey bee colonies establish themselves in natural habitats, often outcompeting native bees for floral resources and nesting spaces.
- Bumblebees (introduced to Tasmania) – While not currently in WA, the spread of bumblebees poses a risk, as they are aggressive foragers that could displace native bee species if introduced.
To safeguard WA’s native bees, conservation efforts such as protecting natural habitats, reducing chemical use, and planting bee-friendly native flora are essential. Encouraging sustainable practices can help ensure these important pollinators continue to thrive.
How You Can Support Native Bees in Your Garden
Creating a bee-friendly garden is one of the best ways to support Western Australia’s native bees. By providing food, water, and shelter, you can help these important pollinators thrive while also enhancing the biodiversity of your outdoor space.
Plant Native Flowering Plants
Native bees rely on local flora for nectar and pollen, so planting WA’s native species will attract and support them. Focus on flowers from the Myrtaceae family, which are well-suited to WA’s environment, including:
- Bottlebrush (Callistemon spp.)
- Eucalyptus (gum trees)
- Tea trees (Melaleuca spp.)
- Grevilleas and Banksias
Different native bee species prefer different flowers, so planting a diverse mix ensures food is available year-round.
Install Bee Hotels and Provide Nesting Sites
Unlike honey bees, most native bees do not live in hives. Providing safe nesting spaces can encourage them to settle in your garden.
- Bee hotels – These small wooden structures with drilled holes or bundled hollow stems offer a home for solitary bees like Leaf-cutter and Resin Bees.
- Leave natural habitats undisturbed – Many native bees nest in the ground, hollow logs, or plant stems, so avoid excessive clearing or heavy mulching.
Avoid Harmful Pesticides and Chemicals
Chemical sprays and pesticides can be highly toxic to bees. To protect them:
- Use natural pest control methods like companion planting and beneficial insects.
- Choose bee-safe organic fertilisers to maintain healthy plants.
- Avoid spraying at all, but especially during flowering periods, when bees are most active.
By making small, thoughtful changes, you can create a native bee sanctuary in your backyard—helping to protect these vital pollinators while enjoying a flourishing garden filled with life.
The Role of Commercial Honey Bees in Ecosystem Balance
The presence of European honey bees in Australia has sparked debate about their impact on native ecosystems. While some concerns exist about competition for floral resources, recent research suggests that honey bees and native bees can coexist, often complementing each other’s pollination efforts.
Coexistence of Honey Bees and Native Bees
Studies have shown that honey bees primarily forage on introduced crops and large-scale flowering plants (Paton, D. C., 1999, Impact of Commercial Honeybees on Flora and Fauna, Publication no. 99/15 Project no. UA-1H), while many native bees specialise in pollinating native wildflowers and smaller blossoms. This division of foraging habits reduces direct competition and can lead to better overall pollination outcomes. Key findings include:
- Honey bees support broad agricultural pollination, ensuring stable food production.
- Native bees contribute to specialised pollination, particularly for certain wildflowers and crops that require buzz pollination.
- Diverse pollinator populations enhance biodiversity, leading to stronger, more resilient ecosystems.
Honey Bees and Australia’s Agricultural Industry
Honey bees are essential to Australia’s food security, supporting the production of:
- Fruit and nut crops, including almonds, apples, and macadamias.
- Vegetable crops, such as pumpkins, cucumbers, and melons.
- Commercial honey production, which relies on WA’s pristine native forests for premium varieties like Jarrah honey and Marri (Red Gum) honey.
By maintaining a balance between commercial honey bee populations and conservation efforts for native bees, Australia can sustain both agriculture and biodiversity, ensuring a thriving environment for all pollinators.
