Five Quick Facts About Australian Native Bees and How to Help on World Bee Day



Bees play an essential role in our ecosystem, contributing to the reproduction of 90 percent of the world's wild flowering plants and 75 percent of food crops. As we celebrate World Bee Day, here are five quick facts about Australian native bees and tips on how you can support these crucial pollinators.

1. Identifying Native Bees

Australia is home to approximately 2,000 species of native bees, distinct from the familiar European honey bee. Alan Dorin from Monash University explains that unlike European bees, many native bees don't make honey, are often stingless, and do not live in large colonies. Notable species include the blue-banded bee and the teddy bear bee, both of which are buzz pollinators that shake flowers to release pollen. In contrast, native stingless bees are small, black, and can be mistaken for flies or ants.

2. Impact of Varroa Mite

The varroa mite, first detected in Australia in June 2022, poses a significant threat to bee populations by spreading viruses that impair bee flight. Efforts to eradicate the mite have shifted to managing its spread, particularly in New South Wales. While the mite primarily affects European honey bees, Australia's native bees, which have thrived for millions of years, continue to be robust pollinators and are less affected by this pest.

3. Technological Advances in Bee Research

Technology, including improved monitoring and AI, has revolutionized the study of bees. Dr. Dorin highlights the use of computer simulations to track pollination behaviors and predict how bees will respond to various conditions. These advancements allow researchers to make informed recommendations to farmers on optimizing crop pollination. Additionally, understanding bees' ability to see UV light helps scientists learn how bees perceive and interact with flowers.

4. Declining Bee Populations

Dr. Caitlyn Forster from the University of Sydney emphasizes that 75 percent of crops rely on pollinators, making the decline in bee populations a significant concern for food security. Native pollinators like hoverflies also play a critical role, though much about their specific contributions remains unknown due to limited research. Unlike commercial honey bees, there is little data on feral honey bee colonies or native bee species populations, leaving many native pollinators unnamed and unstudied.

5. How to Help Bees

Helping bees can be straightforward, especially for those who enjoy gardening. Dr. Forster suggests planting flowers in your garden and reducing the use of pesticides. Bee-friendly plants such as aster, sunflowers, bee balm, coneflowers, lavender, black-eyed susans, and borage provide essential resources for bees. Participating in initiatives like No Mow May, which encourages allowing lawns to grow wild, can also support bee populations.

FAQs

Q: How can I identify Australian native bees?
A: Australian native bees vary in appearance, with some being small and black like the stingless bee, while others, such as the blue-banded bee and teddy bear bee, are more colorful and larger.

Q: What is the impact of the varroa mite on bees?
A: The varroa mite primarily affects European honey bees by spreading viruses. Native Australian bees are less impacted by the mite and continue to be effective pollinators.

Q: How is technology helping bees?
A: Advances in monitoring and AI allow researchers to track bee behavior, predict their responses to environmental changes, and optimize pollination strategies for farmers.

Q: Why are declining bee populations a concern?
A: Declining bee populations threaten food security as 75 percent of crops depend on pollinators. Limited research on native pollinators further complicates understanding their impact.

Q: What can I do to help bees?
A: Plant bee-friendly flowers, reduce pesticide use, and participate in initiatives like No Mow May to create supportive environments for bees.
