A massive previously unknown stick insect has been discovered in Australia’s high-altitude rainforest. This may be the heaviest insect ever recorded in the country.
A giant creature, the researchers named Acrophylla Alta, grows to approximately 16 inches (40 cm) long. The giant insect lives in the inaccessible tree canopy of the tropical northern Queensland.
Researchers recorded A. Alta in a recent study published in the journal Zootaxa on June 17th, describing it as a “magnificent new species.”

A new species of stick insects, about the same weight as golf balls were found in remote rainforest canopies in northeastern Australia, was announced Thursday. Scientists believe that the winged insect, Acrophila Alta, is the heaviest ever.
It is not the longest stick insect in Australia. That honor reaches a length of about 22 inches (57 cm) and A. It is sent to a Gargantuan Stick insect (Ctenomorpha gargantua), who lives in the same area as Alta. However, A. The Alta is heavy.
“There’s a long stick insect out there. [in the region]but they have a fairly light body,” said Angus Emmott, a researcher at James Cook University in Australia, in a statement. “From what we know, this is Australia’s heaviest insect.”
One individual in the study was overwhelmed by about 1.6 ounces (44 grams). Research shows that it weighs almost twice as much as a mature female gangaantounstick insect filled with eggs previously recorded by researchers.

Researchers discovered A. Alta in the Tableland area of North Queensland, 1,600 to 3,900 feet (500 to 1,200 meters) above sea level. A. Alta clearly appears to be eating the leaves of forest canopies, and research shows that they are usually unaware of humans.
“It is confined to small areas of highland rainforests and is high in the canopy,” Emmott said. “So, unless you get a cyclone or bird that has fallen, a very small number of people can see them.”
The creature’s huge size may be related to its ability to survive in colder, higher altitude environments. This fits an evolutionary trend called the Bergmann rule, which states that animals evolve to grow in colder climates. Not all animals follow Bergmann’s rules and it is unclear how much they apply to insects, but the idea that the surface area to volume ratio for large animals is small and can help reduce heat loss is A. That alta will benefit.
“It’s the cool, wet environment they live in,” Emmott said. “Their weight could help them survive the cold, which is why they have evolved into this big insect over millions of years.”
