- Found on the Atherton Tablelands, the Acrophylla alta species is the heaviest insect in the country
- It measures 40 centimeters and weighs 44 grams, similar to a golf ball.
- Its large size is the result of an adaptation to the cold and humid habitat
- The discovery provides new insights into Australian biodiversity
Imagine walking through the thick of a forest and suddenly seeing how a branch begins to move It may seem like something out of a movie, but in northern Australia, this scene is yet another example of how surprising nature can be. And a team of Australian scientists has recently documented the discovery of a giant stick insect never before observed in this territory.
The research, published by experts from the James Cook University, confirms the existence of a new species baptized as Acrophylla altaThe specimen was detected high in the trees of the Atherton Plateau, a remote area covered in tropical rainforest in far north Queensland. This is an insect that has aroused international interest., since it has been recognized as Australia's heaviest, weighing 44 grams and measuring 40 centimetres in length.
Professor Angus Emmott, who leads the study, argues that the unusual size This insect's characteristic is due to its adaptation to its "cold and humid habitat." They suspect that the additional body mass makes it easier to survive in lower temperatures. and in adverse conditions during the region's prolonged rainy seasons.
The discovery was made in a small area of high-altitude rainforest, an ecosystem difficult for humans to access. Emmott himself comments that seeing one in the wild is rare, as they typically live in treetops and only fall to the ground after intense events, such as cyclones or a bird attack.
A master of camouflage and Australian record weight
On stick insects They were already known for their extraordinary ability to go unnoticed, perfectly imitating branches and leaves to escape their predators. This skill, which they have perfected over millions of years, has allowed them to colonize diverse ecosystems. However, Never before has such a robust specimen been recorded in Australia.
According to researchers, although there are longer species in other regions of the world, none in the country reaches this weight. The world record remains in the hands of the New Zealand giant weta, which can exceed 70 grams, according to the Guinness World Records; This Australian discovery represents an unprecedented milestone at the local level.
In addition to size, one of the aspects that has most caught the attention of scientists is the eggs of the species. Each one presents unique shapes and textures, which facilitated its differentiation from other known species and was key to the classification of this new stick insect.
A hidden life high in the forest
The restricted habitat of Acrophylla alta explains why this insect had remained unidentified until now. Being almost always found in the highest part of the forest canopy and in such a limited region, contact with humans is practically anecdotalOnly two copies have been preserved and they are already They are part of the Queensland Museum's collection for study and future conservation.
Reproductive biology is also unique: The mating process can last for daysAnd including Males remain with the female for weeks, ensuring the continuity of the species. The Egg development can extend up to 12 months before they hatch.
Implications for biodiversity and ecosystem studies
This unusual discovery provides essential information about Australia's biological diversity. and the need to gain a deeper understanding of less-explored environments. As researcher Emmott emphasizes, "To protect an ecosystem, it's first essential to know which species live there and how they interact."
The discovery of Acrophylla alta also It rekindles interest in Australian wildlife and highlights the importance of continued research in less-traveled areas.The specimens studied could be key to future research on the evolution and adaptation of stick insects in extreme habitats.
This discovery in such an isolated area of Australia represents significant news for national entomology and Evidence that there is still much to be discovered in the most remote corners of the planetThe study of this imposing giant stick insect promises to shed light on the evolutionary processes and mechanisms that allow fauna to adapt to the challenges of the natural environment in which they live.
