A Stick Insect. Whatever You Call It, It’s Not Extinct

A Stick Insect. A Tree Lobster. Whatever You Call It, It’s Not Extinct

A genetic analysis showed that a stick insect found on another island was the same species as one that had been wiped out by rats on Australia’s Lord Howe Island.

 The tree lobster, one of the rarest insects on Earth, has lived a rather twisted life story.

Scientifically known as Dryococelus australis, this six-inch-long stick bug with a lobster-esque exoskeleton once occupied Lord Howe Island in the Tasman Sea, between Australia and New Zealand.

In 1918, rats escaping a capsized steamship swam ashore. The tree lobsters became rat chow. Two years later, all tree lobsters seemed to have vanished, and by 1960 they were declared extinct.
