Phasmatodea and Orthoptera
The Orthoptera (from the Greek orthos = "straight" and pteron = "wing") are an order of insects with paurometabolous or incomplete metamorphosis, including the grasshoppers, crickets and locusts. Many insects in this order produce sound (known as a "stridulation") by rubbing their wings against each other or their legs, the wings or legs containing rows of corrugated bumps. The tympanum or ear is located in the front tibia in crickets, mole crickets, and katydids. These organisms use vibrations to locate other individuals.
The Phasmatodea are an order of insects, whose members are variously known as stick insects (in Europe), walking sticks (in the United States of America), ghost insects and leaf insects (generally the family Phyliidae). The ordinal name is derived from the Greek "phasma" meaning an apparition or phantom, and refers to the resemblance of many species to sticks or leaves.
Beetles are a group of insects which have the largest number of species. They are placed in the order Coleoptera, which means "sheathed wing" and contains more described species than in any other order in the animal kingdom, constituting about twenty-five percent of all known life-forms
A cicada is an insect of the order Hemiptera, suborder Auchenorrhyncha, in the superfamily Cicadoidea, with large eyes wide apart on the head and usually transparent, well-veined wings. There are about 2,500 species of cicada around the globe, and many remain unclassified. Cicadas live in temperate to tropical climates where they are among the most widely recognized of all insects, mainly due to their large size and remarkable acoustic talent
