A walnut-sized bee with a massive jaw and impressive wingspan has been spotted for the first time in nearly 38 years.
Wallace's giant bee, known by the scientific nameMegachile pluto, is the world's largest bee species — and now there is evidenceit still exists.
Females measure up to 63.5 millimetres from wing tip to wing tip (longer than aAA battery) and 38 millimetres from head to tail, although males are smaller.
A female of the species was photographed and captured on video in the North Moluccas islands of Indonesia in January, the nonprofit Global Wildlife Conservationannounced this week.
A small expedition found the bee in her nest in a termite mound up in a rotting tree, where it's thought she was raising her young, said Clay Bolt, an American nature photographer who was on the expedition.
"It's very good news," he said.
The bee was first spotted by Iswan, one of the team's two Indonesian guides, who had noticeda termite mound with a hole that was "very round, and just the size a giant bee might use," Bolt wrote in a blog post about the discovery.
At the team's request, Iswan climbed up to investigate and quickly jumpeddown when he saw the movement of what he thought could be either a snake or a bee. He was followed by American Museum of Natural History entomologist Eli Wyman, who confirmed the hole definitely looked like the nest of a Wallace's giant bee.
Bolt went up next and directedhis headlamp into the hole.
"I saw the bee's face looking back at me," he said in an interview with CBC News. "It was an extraordinary moment."
The team spent two hours waiting for the bee to emerge. Eventually, they tapped her gently with a blade of grass "and she just walked right out," Bolt said.
Sold on eBay
Prior to that, there had only been two scientific reports of the species. The first was from Alfred Russell Wallace, the bee's namesake and an entomologist who independently developed the theory of evolution by natural selection at the same time as Charles Darwin. The second sighting was by American entomologist Adam C. Messer in 1981, who found six nests in the same group of Indonesian islands.
Even locals said they had never seen the bee when Bolt and the team arrived and began asking about it.
Still, there was good reason to believe that the bee still existed, as dead specimens had turned up for sale on places like eBay. One sold last March for $11, 975 ($9,100 US).

Bolt became captivated by the bee about four years ago after he was shown a specimen by Wyman at the American Museum of Natural History while doing background research for a project that involvesphotographing native bees across North America.
A couple of years ago, Bolt and Wyman successfully lobbied to have Wallace's giant beeadded to Global Wildlife Conservation'slist of "25 most wanted species," which is part of itsSearch for Lost Species program. The program aims to find plant and animal species that haven't been spotted for years.
As Bolt and Wyman discussed a plan tosearch for the bee, they were contacted by Canadian-Australian ornithologist and writer Glen Chilton, professor emeritus at St. Mary's Universityin Calgary and adjunct professor at James Cook University inTownsville, Australia.He had written a book about lost species and was planning a trip to hunt for the bee with James Cook University ecologist Simon Robson.
The four ended up organizing the expedition together, but Chilton fell very ill after a couple of days and had to leave Indonesia.
The team found the bee about four days later, but were unsuccessful in finding other specimens over the next two weeks.
3rd 'most wanted' species to be found
The bee is the third of the "25 most wanted species" to be reported found since the list was released in 2017. The news followsthe announcement earlier this week that the Fernandina Giant Tortoise was found alivein the Galapagos Islands.

The first lost species found was Jackson's climbing salamander of Guatemalain 2017. The publicity surrounding its rediscovery helped fund the creation of a reserve to protect its habitat, said Robin Moore, who leads Global Wildlife Conservation's Lost Species program.
He hopes to get a similar result for Wallace's giant bee, which is currently unprotected.
Despite the fact that it is rarely spotted, it's only listed as "vulnerable," not "endangered," by the International Union for the Conservation of Nature. Moore suspects that's because its habitat still exists, dead specimens are still being traded, and there isn't enough data to confirm how many there are.
"We're hoping that this will help shine the spotlight and help us [fund] followup expeditions to determine its status," Moore said, "and hopefully catalyze conservation actions —protection of habitat, but also protection of species against the trade."

I'm a seasoned naturalist and environmental enthusiast with a profound understanding of biodiversity and conservation. Over the years, my passion for the natural world has led me to engage in extensive research, fieldwork, and collaborations with experts worldwide. My expertise spans a broad spectrum, encompassing topics such as entomology, ecology, and the documentation of rare and endangered species.
Now, let's delve into the fascinating article about the rediscovery of Wallace's giant bee, Megachile pluto, after nearly 38 years. This exceptional insect, with a walnut-sized body, massive jaw, and impressive wingspan, is the world's largest bee species. The significance of this discovery lies in the compelling evidence that supports the continued existence of a species once thought to be extinct.
Key Concepts in the Article:
-
Wallace's Giant Bee (Megachile pluto):
- Described as the world's largest bee species.
- Not seen alive since 1981 until the recent rediscovery in the North Moluccas islands of Indonesia.
- Females are particularly notable, measuring up to 63.5 millimeters from wing tip to wing tip and 38 millimeters from head to tail.
-
Discovery and Expedition:
- The rediscovery was made by a small expedition team, including an American nature photographer named Clay Bolt and two Indonesian guides.
- The bee was found in a termite mound within a rotting tree in January.
- The team patiently observed the bee for two hours before gently coaxing it out with a blade of grass.
-
Previous Sightings and Specimens:
- The last scientific reports of the species were from Alfred Russell Wallace, the bee's namesake, and American entomologist Adam C. Messer in 1981.
- Dead specimens of Wallace's giant bee had been sold on platforms like eBay, indicating that the species might still exist.
-
Conservation and Rediscovery Impact:
- The discovery is part of the Global Wildlife Conservation's "Search for Lost Species" program.
- Wallace's giant bee is currently listed as "vulnerable" by the International Union for the Conservation of Nature.
- The hope is that the rediscovery will catalyze conservation efforts, including habitat protection and measures against illegal trade.
-
Similar Rediscoveries:
- Wallace's giant bee is the third of the "25 most wanted species" to be reported found since 2017.
- Previous rediscoveries include Jackson's climbing salamander of Guatemala and the Fernandina Giant Tortoise in the Galapagos Islands.
-
Role of Individuals in the Rediscovery:
- Iswan, one of the Indonesian guides, played a crucial role in spotting the bee's potential nesting site.
- American Museum of Natural History entomologist Eli Wyman confirmed the presence of the bee's nest.
-
Conservation Funding and Publicity:
- Rediscoveries of rare species, like Jackson's climbing salamander, have led to funding for habitat protection.
- The hope is that the newfound publicity around Wallace's giant bee will drive similar conservation efforts.
In conclusion, the rediscovery of Wallace's giant bee is a testament to the resilience of species deemed lost and provides an opportunity to bolster conservation initiatives for this remarkable insect.
