Origins

Leaf insect (Phasmida Phylliidae) belongs to the family Phylliidae, order Phasmatodea. It lives in tropical and subtropical areas worldwide, but the densest population may lie in Southeast Asia and Australia.

Are called leaves or leaves that go-reaching. Until now described 37 species in four genera.

A leaf insect fossils dating back 126 million years old was discovered by a team of researchers. It is the oldest known insect leaf. It was discovered in Liaoning Province in China.

It consumes buds, various leaves and sick leaves, and by preparing the ground for next year defecation.

Like stick insect is an insect herbivores.

Features Leaf-insect

Leaf insect males can reach a length of 8cm and 12cm females. The male body has small holes in the lower body while the female has small stratii.

Most insects of this kind on camouflage remained motionless, almost immovable, because they are nocturnal. Their bodies best mimic leaves.

They are considered the most spectacular species copycat world. These insects camouflage so well that it is almost impossible to see them through tree branches. To move the day move slowly and waved to simulate the movement of a leaf in the wind.

If attacked by predators and is trapped leg can give to him to save his life. Foot regenerate the tail lizard while. Only males can fly, not females.

Females can reproduce without male help. Unfertilized eggs deposited by females produce female insects leaf. They can deposit thousands of eggs during this period.

Because this process that females can replicate single number is much larger than the males. So the ratio is one male to 500 female 20, depending on the area.

From eggs deposited by the female black nymphs hatch red-brown. After the first moult starts to become green and when mature or be completely green except for a few brown spots.

The advantage of the leaf insect eggs have a bulge is that the ants eat. So ants carry the eggs in their mounds bulge and thus consume the eggs are protected from predators.

Life expectancy is different. If males live at most a few weeks, the females live 6-10 months.
