On World Stick Insect Day we celebrate the rediscovery of the world's most endangered insect, the Lord Howe Island phasmid Dryococelus australis.

When small species are left alone to evolve for centuries on small islands, they often become larger. Quietly, over thousands of years, Dryococelus australis grew to a great size on Lord Howe Island, in the Tasman Sea between Australia and New Zealand. But the peaceful life of the Lord Howe Island stick insect, an invertebrate of such gargantuan proportions that it is also fondly known as the tree lobster, was destroyed by European settlers. In 1918, a shipwreck brought black rats to the island. The flightless insects were once so common they were used by settlers as bait for fishing, but the rats wiped out the entire population on the island in just two years. In 1964, a group of climbers attempting to scale Ball’s Pyramid, a spectacular pinnacle of basalt jutting from the ocean 20km (12 miles) off the coast of Lord Howe Island, discovered and photographed the sausage-sized carcass of one of the insects. They failed to reach the top but subsequent climbing attempts found more stick insect bodies – just never a live one. Tantalised by these sightings, in 2001, the Australian scientists David Priddel and Nicholas Carlile made their way to the island. At first they...
