The Phaneropterinae, the sickle-bearing bush crickets or leaf katydids, are a subfamily of insects within the family
Tettigoniidae
Insects in the family (biology), family Tettigoniidae are commonly called katydids (especially in North America) or bush crickets. They have previously been known as "long-horned grasshoppers". More than 8,000 species are known. Part of the subo ...
. They are also known as false katydids or round-headed katydids.
The name Phaneropterinae is based upon the Old World genus '' Phaneroptera'' (type species '' P. falcata''), meaning "visible wing"; this refers to the exposed tips of the inner wings seen in many species, although some genera, notably in the tribes

Arboreal locomotion is the locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally (scansorial), but others are exclusively arboreal. The hab ...
in habitat. The vast majority of species live in shrubs and trees, feeding on leaves and twigs. Some species might potentially cause significant damage, though usually superficial, when present in large numbers, but this is rare; they usually are solitary, unlike meadow grasshoppers, so much so that they seldom come to human notice.

The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs. In insects, an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typica ...
and male genitalia vary according to the genus. The Phaneropterinae differ from other subfamilies of Tettigoniidae (and other Orthoptera) in their oviposition; their eggs are rarely deposited in the earth, but are either glued in double rows to twigs, or are inserted in the edges of leaves.

The subfamily Phaneropterinae was first erected in 1838 by German
zoologist
Zoology ( , ) is the scientific study of animals. Its studies include the structure, embryology, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. Zoology is one ...
