The world's rarest insect

Dryococelus australis
is a stick insect or tree lobster, species that live in the Lord Howe Island Group. It is considered the rarest insect on our planet. It is the only monotypic member of Dryococelus and was thought to have died out by 1920. However, it was rediscovered in 2001. It has been extincted from Lord Howe Island, its largest habitat. The rediscovered population of 24 individuals was located on Ball's Pyramid.

Stick insects were once common on Lord Howe Island. They were used to baitfish. It was believed that they became extinct after the supply ship SS Makambo ran aground in 1918 on Lord Howe Island, allowing black rats the opportunity to establish themselves. Stick insects were not found after 1920. In 1964, however, a group of climbers visited Ball's Pyramid 23 km southeast of Lord Howe Island and found a dead Lord Howe Island stick insect. Climbers discovered a few more dead insects in subsequent years but failed to locate any live specimens.
