The Phaneropterinae are a subfamily of bush crickets or katydids belonging to the family Tettigoniidae; nearly 2060 species in 85 genera throughout the world are known. They are among the largest winged katydids.
The name Phaneropterinae is based upon the Old World genus Phaneroptera, meaning "visible wing", referring to the exposed tips of the inner wings.
Their legs vary from genus to genus, but the front and middle ones are always much shorter than the hind ones. The ovipositor and male genitalia are also variable depending on the genus.
These katydids are arboreal in habitat with the vast majority of them passing their lives in shrubs and trees, feeding on leaves and tender twigs with a potential for causing much damage when present in large numbers. This is rare, however, as they live a solitary life unlike meadow grasshoppers, thus are seldom noticed by man. The Phaneropterinae differ from locusts in their habits of oviposition. Their eggs are rarely deposited in the earth or twigs, but are either glued fast in double rows to the outer surface of slender twigs or are inserted in the edges of leaves.
