As the Australian summer heats up, so does the activity in our backyards, and not just from the barbecues and cricket games. A recent spectacle has caught the attention of garden enthusiasts and entomologists alike, as thousands of beetles have been spotted in what appears to be a 'mating swarm' on lawns along the east coast.

A Melbourne local was the first to bring this phenomenon to light, sharing footage of the incredible number of plague soldier beetles congregating at Queens Park in Moonee Ponds. The sight was so unusual that it prompted a flurry of social media inquiries and confusion, with many Australians admitting they had never witnessed anything quite like it.


But before you start worrying about a beetle invasion, Dr. Tom White, an entomologist at Sydney University, has some reassuring words. Speaking to Yahoo News Australia, Dr. White explained that these beetles are not only harmless but are actually beneficial to our ecosystem.


Why should we care about plague soldier beetles, you ask? Well, as adults, these beetles are avid pollinators. They feast on nectar and pollen, playing a crucial role in fertilizing a wide array of flowering plants. This pollination is not just about keeping our gardens looking pretty; it's vital for maintaining biodiversity and supporting the production of crops that we rely on for food.


'They're native to Australia, and what you're seeing there is almost certainly a mating swarm, which is common at this time of year as the weather warms up,' Dr. White told Yahoo. 'They’re actually great for the garden since the adults are enthusiastic pollinators which feed on nectar, and their larvae prey upon small pest insects, so it’s a double-win,' he added.

Dr. White also pointed out that the beetles contribute to natural pest control. They are 'chemically defended,' meaning they produce substances that are toxic or repellent to predators, but they are 'perfectly harmless to humans.' They might taste nasty to lizards and birds, but for us, they pose no threat.

So, if you come across a gathering of these beetles, Dr. White suggests enjoying the natural spectacle and leaving them be. Despite their somewhat alarming name and tendency to form large swarms during mating, they are harmless to humans and crops, making them an ecologically valuable species.


As we continue to marvel at Australia's weird and wonderful environment, it's important to remember that not all insects are pests. Some, like the plague soldier beetle, play a pivotal role in our ecosystem. So next time you spot a swarm of these creatures in your backyard, take a moment to appreciate the important work they do.
