San Diego Zoo Hatches First ‘Tree Lobster’ Insects in the U.S.


The almost-extinct ‘Tree Lobster’ insects have recently hatched in the San Diego Zoo on February 6th, having the zoo receive more than 19 nymphs, according to

“This giant stick insect was once confined to one habitat, the Lord Howe island, near Australia. Rat infestation, as a result of a shipwreck near the island, caused a drop in its population and near extinction of dryococelus australis, the stick insect,” stated.

“The eggs arrived in San Diego as part of an ongoing conservation effort to bring the tree lobster back from the brink of extinction. The huge insect, which can grow to a length of around 7 inches, was previously thought to be extinct, until its rediscovery in 2001,” reported.

A few years ago, the San Diego Zoo tried to hatch the eggs, but it turned out to be unsuccessful. They figured out later that they needed to get clippings from Australia and grow a bunch of these bushes in order to hatch the insects, according to

More eggs should keep hatching over the next few months, since the “Tree Lobster” insects are of staggered ages, according to
