Lord Howe Stick Insect Physical Description
The breathtaking Lord Howe Stick Insect also has the ability to grow to a maximum known length of about 8 in (20 cm).
However, the remarkable species also displays a moderate degree of sexual dimorphism, with females averaging 20% smaller than males.
Individuals have a rather elongated, sturdy shape. The larger males also tend to have thicker thighs than females.
Unlike most related species, this creature possesses no wings, but does have the ability to run rather quickly along the ground.
Colors also vary between individuals, without regard to gender. These include various shades of black, brown, and reddish.
Species: D. australis
Lord Howe Stick Insect Distribution, Habitat, and Ecology
The mesmerizing Lord Howe Island Stick Insect currently only lives on the tiny island named Ball’s Pyramid.
It consists of little more than steep volcanic rock, inhabited by only a few rather small shrubs, and one tiny colony of this insect.
So, the entire surviving population of the Lord Howe Island Stick Insect literally lives under one such small bush.
Uniquely, and perhaps fortuitously, the females also have the ability to reproduce through parthenogenesis.
