Sorry but that information is classified because they were recently rediscovered.
The giant stick insect, or Lord Howe Island phasmid, disappeared from Lord Howe Island primarily due to the introduction of the black rat in 1918, which preyed on the insect and other native fauna. Habitat destruction and human activities also contributed to its decline. By the 1920s, the species was believed to be extinct, until it was rediscovered in 2001 on Ball's Pyramid, a steep, rocky islet south of Lord Howe Island. Conservation efforts are ongoing to help restore its population.
