Gigantic, Unprecedented Stick Insect Found in Anticipated Location Revealed
In the high-altitude rainforests of the Atherton Tablelands, located in northeastern Australia, a new stick insect species has been discovered. Named Acrohylla alta, this insect is notable for its impressive size and weight, making it likely the heaviest insect in Australia.
The researchers who made the discovery, Professor Angus Emmott from James Cook University and others, suggest that the insect's large size may be an evolutionary adaptation to its cool, wet, high-altitude environment. This adaptation helps the insect survive colder conditions over millions of years. The remote and difficult-to-access habitat has also likely contributed to the species remaining undiscovered until now, as it lives high in the rainforest canopy, rarely coming down except after events like cyclones or predation by birds.
Distinctive features that helped scientists identify Acrohylla alta as a new species include its unique egg characteristics, which differ in surface texture, shape, and other traits from other stick insect species. The discovery was prompted by a strange photograph of an unknown species sent to Angus Emmott and Ross Coupland.
So far, only two female specimens have been found. Professor Emmott hopes to find a male specimen to learn more about the species' reproduction and lifecycle. The discovery of Acrohylla alta highlights the vast amount of unknown species in ancient rainforests, as stated by Peter Valentine, an environmental scientist at James Cook University.
The discovery of Acrohylla alta has significance for biodiversity knowledge and ecosystem conservation efforts in the Wet Tropics of Queensland. However, concerns have been raised about the preservation of rainforests in light of new species discoveries. Both Emmott and Valentine express concern that many species may be lost before they are even discovered, particularly in the world of invertebrates.
Acrohylla alta is approximately 15 inches (40 centimeters) long, similar to the height of a bowling pin, and weighs around 44 grams, slightly lighter than the heaviest golf ball. This discovery adds to the growing body of knowledge about the incredible diversity of life in Australia's rainforests.
