Giant Stick Insect

Description:

The Phasmatodea (sometimes called Phasmida or Phasmatoptera) are an order of insects, whose members are variously known as stick insects (in Europe and Australasia), walking sticks or stick-bugs (in the United States and Canada), phasmids, ghost insects and leaf insects (generally the family Phylliidae). The stick insect resembles the twigs among which it lives, providing it with one of the most efficient natural camouflages on Earth. It and the equally inconspicuous leaf insect comprise the Phasmida order, of which there are approximately 3,000 species. Stick insect species, often called walking sticks, range in size from the tiny, half-inch-long (11.6-millimeter-long) Timema cristinae of North America, to the formidable 13-inch-long (328-millimeter-long) Phobaeticus kirbyi of Borneo. This giant measures over 21 inches (55 centimeters) with its legs outstretched, making it one of the world’s longest insects. Females are normally larger than males. Phasmids generally mimic their surroundings in color, normally green or brown, although some species are brilliantly colored and others conspicuously striped. Many stick insects have wings, some spectacularly beautiful, while others resemble little more than a stump.

Habitat:

Phasmatodea can be found all over the world in warmer zones, especially the tropics and subtropics. The greatest diversity is found in Southeast Asia and South America, followed by Australia. Found predominantly in the tropics and subtropics—although several species live in temperate regions—stick insects thrive in forests and grasslands, where they feed on leaves. Mainly nocturnal creatures, they spend much of their day motionless, hidden under plants.
