Discover Australia’s Heaviest Insect Ever: 44-Gram Stick Insect Found in Remote Rainforest

In a secluded rainforest of Australia, teeming with venomous creatures, researchers have unearthed a new stick insect species that they suspect is the heaviest ever documented in the country. Weighing approximately 44 grams, equivalent to a golf ball’s weight, and spanning 40 cm in length, this discovery has left scientists intrigued.

Dr. Angus Emmott from James Cook University played a significant role in identifying this new Acrophylla alta species. According to a press release, he attributed the insect’s substantial size to its adaptation to the cool, moist environment it inhabits. He stated that the insect’s robust physique likely enables it to endure the colder conditions, thus evolving into such a large creature over millennia.

“This could well be Australia’s heaviest insect,” Dr. Emmott was quoted as saying.

The new stick insect was found nestled within the canopies of the mountainous Wet Tropics region in Far North Queensland, located in northeastern Australia. The remote location may have contributed to its elusive nature, with Dr. Emmott suggesting that its restricted habitat and high-altitude dwelling make it difficult for humans to access without extreme weather events or birds accidentally bringing one down.

The unique characteristics of the insect’s eggs also helped scientists confirm it as a new species. Dr. Emmott explained that every stick insect species possesses distinct egg features, including varying surfaces, textures, and indentations, as well as unique shapes and caps.

Two specimens of this newly discovered species have been added to the Queensland Museum’s collection for future study and research.
