They became extinct on Lord Howe island when a ship ran aground in 1918 releasing introduced black rats to the island. These rats found the large resident stick insects very tasty and wiped them out quickly. By 1930 the species was declared extinct
Researchers removed a male and female from Balls Pyramid and brought them to Melbourne Zoo. Thanks to the determined efforts of the invertebrate keepers this pair was successfully bred and in 10 years over 9,000 stick insects have been born that descend from this single pair.
- These insects can measure up to 15 cm long with females being slightly larger.
- They have been called the 'Land Lobster' due to their unusual appearance
- They are mostly nocturnal in nature
- Females are able to breed without the need for males. This is known as 'Parthenogenesis' and is fairly common with stick insects. When this occurs the offspring will all be female and effectively a clone of their mum.
- In 2012 Melbourne Zoo are giving 20 schools the opportunity to breed this species in the classroom.
- Efforts are underway to remove the introduced Black Rats from Lord Howe
Island so the captive-bred stick insects can one day soon be re-introduced.
- Any random event (e.g. a rock slide) could wipe out the entire population
- Illegal collection: access to Balls Pyramid is currently restricted to prevent poaching
- Invasive weeds: Morning Glory is encroaching on the few shrubs that provide habitat to the population on Balls Pyramid
- Balls Pyramid is very vulnerable to disturbance. Access to the site is tightly restricted to protect the environment
