Acrophylla alta, a newly discovered stick insect in Australia, measures 41cm and weighs 44g. Its significant size prompted questions regarding its previous invisibility to scientists. Stick insects possess exceptional camouflage, mimicking various natural elements such as leaves, branches, and moss, making them difficult to detect. Their ability to remain motionless or fall to the ground further complicates spotting them. The species was identified following a photograph posted on iNaturalist, prompting scientists to search the rainforest at night for this elusive insect.
The enormous stick insect, Acrophylla alta, measures 41cm in length and weighs 44g, making it difficult for scientists to spot due to its excellent camouflage.
The evolution of phasmids into various shapes and appearances showcases the effectiveness of natural selection, with over 3,500 species adapting to look like sticks or leaves.
Stick insects employ advanced forms of camouflage to evade predators, often becoming indistinguishable from their surroundings, a strategy honed through over 100 million years.
Scientists were able to discover this new species after a photo posted on iNaturalist led them to search through a rainforest for several nights.
