I discovered a new Australian native bee, but there are still hundreds we need to identify
- Written by The Conversation
The female of the species has devil-like black horns, and a taste for extremely rare pollen. But until now, this Australian native bee has never been officially named or identified.
My discovery of Megachile (Hackeriapis) lucifer, underscores the lack of knowledge and investment in Australia’s unique native bees.
Whilst considerable funding and attention has been focused on the introduced European honey bee, Apis mellifera, there are still hundreds of native bees that are yet to be identified and named.
How was this bee found?
This fascinating new megachile (or leaf cutter) bee was first discovered while on a surveying trip in the Bremer Ranges in the goldfields region of Western Australia in 2019.
I was conducting surveys for pollinators – such as bees, other insects, flies and wasps – of a critically endangered plant called Bremer marianthus, or Marianthus aquilonaris, which is only known in this region.
Sadly, as is common for many threatened plant species, the pollinators for this straggly shrub with blue-tinged white flowers were completely unknown. One of the native bees collected on this visit immediately caught my attention because the female had large devil-like horns protruding from her clypeus – the broad plate on the front of a bee’s head.
When I investigated, it was clear this wasn’t a species that had been found before. Whilst some native bees have horns or prongs, none have the large and slightly curved horns of this one. Comparing it with museum specimens, along with DNA barcoding, confirmed this species was new to collectors and to science.
DNA barcoding also revealed a male native bee I had collected at the site was her partner, but he lacked horns. This is the opposite of the situation in much of the animal kingdom, where the males are more likely to be amoured.
Bringer of light
When you discover a new species, you have the honour of choosing a name. The first new species of native bee I “described” (or scientifically identified) in 2022, Leioproctus zephyr, is named after my dog, Zephyr. For this new species, the horns meant the name Lucifer was a perfect choice.
Lucifer is also Latin for “light bringer”, and I hope this new species brings to light the wonders of our native bees.
Australia has more than 2,000 species of native bees. They help keep our ecosystems healthy and play a crucial role in pollinating wildflowers.
We need to understand native bees
This new native bee, Megachile lucifer, is only one of an estimated 500 native bees that are not described. Far more attention has been given to the introduced European honey bee Apis mellifera. Whilst the honey bee is important for crop pollination, this species is not threatened, and can in fact harm our native bees.
The truth is honeybees compete with native animals for food and habitat, disrupt native pollination systems and pose a serious biosecurity threat to our honey and pollination industries.
Currently, there no requirement to survey for native bees in areas about to be mined, farmed or developed. Even if they are found, any species that has not been officially identified it has no conservation standing, which is one reason why taxonomic research is so important.
Protect the pollinators
Megachile lucifer was collected on a flowering mallee plant that attracted thousands of native bees and other insects. In subsequent years of surveying this site, the mallee was not flowering, Megachile lucifer was not seen, and far fewer insects were recorded.
With no monitoring of native bees, we also don’t know how their populations are faring in response to threatening processes, like climate change.
More interest and investment into the taxonomy, conservation and ecology of native bees, means we can protect both them and the rare and precious plants they pollinate.
