Giant Stick Insect Species Discovered in Australia

A new giant stick insect species has been identified in the rainforests of North Queensland, adding to Australia’s remarkable record of unique wildlife discoveries. The insect, named “Acrophylla alta”, is believed to be the heaviest stick insect ever recorded in the country.

Discovery in the Queensland Rainforest

Researchers uncovered the species during field studies in the mountain rainforests of tropical North Queensland. Despite its impressive size, the insect remained unknown for years due to its camouflage and its habitat high in the forest canopy, an area rarely accessible to scientists.

Size and Distinctive Characteristics

The species can grow up to 40 centimetres in length, making it one of the largest insects found in Australia. Early examinations suggest that its heavy body mass sets it apart from other long but lightweight stick insects in the region. One specimen studied weighed around 44 grams, making it significantly heavier than previously recorded giants.

Habitat and Ecological Adaptation

“Acrophylla alta” inhabits altitudes between 500 and 1,200 metres in cool, wet rainforest environments. Scientists believe its large size aligns with Bergmann’s rule, which proposes that animals in colder climates evolve larger bodies to retain heat. Its remote and elevated habitat further explains why the species remained undetected.

Exam Oriented Facts

• “Acrophylla alta” was discovered in North Queensland’s high-altitude rainforests.
• It may be the heaviest stick insect recorded in Australia.
• The species can grow up to 40 centimetres long.
• Its size is thought to be an adaptation to cool, high-altitude conditions.

Significance of the Discovery

The identification of “Acrophylla alta” highlights the rich biodiversity of Australia’s rainforests and the potential for more hidden species in remote ecosystems. The finding underscores the importance of continued ecological research to uncover the lesser-known inhabitants of these diverse natural landscapes.
