Only three female Ctenomorpha gargantua stick insects have ever been seen in the wild. Females are always bigger and can grow up to 61.5 cm (2.02 ft).
The insect is so rarely seen as it lives in the top canopy of the tall and dense north Queensland tropical rainforests of Australia. The species was first seen in photographs taken at Malanda in 2000.
So far, “almost nothing is known about the biology or ecology of the species in the wild”, say Maik Fiedel, coordinator of live exhibits at the Museum Victoria’s Melbourne Museum, where a captive breeding program is run.
