Rare Peppermint Stick Insect - Cape Tribulation Australia - Photo 11 - One Fine Spray Jet Can you See?

The Peppermint Stick Insect (Megacrania batesii) has a very small and patchy distribution along some beach areas in Cape Tribulation, Etty Bay and Mission Beach. They range in colour from bright green to turquoise and they feed only on a few species of Pandanus plants and these spikey-leaved palms also provide some shelter from predators. The Peppermint Stick Insect spends all its time on the Pandanus, feeding, sheltering, mating and laying its eggs on the leaves where they roll down to the tight-fitting leaf axil to 'incubate'. Why is it called the Peppermint Stick Insect? As a defense mechanism, it sprays an irritating fluid at any predators (which include curious tourists) and this fluid smells like peppermint. This is a strenuous act for the frightened stick insect so if you are lucky enough to find one in your travels through the Wet Tropics, please don't try to touch it.

Tour operators, especially at Cape Tribulation, have been observed pulling back leaves and poking the insect to provoke a minty reaction. Nature lovers say this stresses the insect and damages the pandanus.

Most species of stick insects live in the trees, feed on the leaves and look just like a branch. The easiest way to pinpoint one is to look for a branch that seems out of alignment to the other branches or a branch that appears to be attached to the outside edges of leaves.

The female's body is much larger than the male's and both have wings - but the males' wings are larger. Females don't travel around much and emit a hormonal perfume (called a pheromone) to attract the males to them for breeding. The males have larger wings to enable them to fly longer distances in search of females.

Although the stick insects are well camouflaged to aid their invisibility to predators such as birds, their wings provide a backup defence system. Normally, their wings fold up very neatly along the body but the stick insect can spring the wings out suddenly. The colours of stick insect wings can be vivid colours which can startle a potential predator momentarily - just long enough to enable the stick insect to fly away.
