Conocephalus

Conocephalus is a genus of bush crickets, known as coneheads (a term also sometimes applied to members of the related genus Ruspolia). It was described by Carl Peter Thunberg in 1815.

Description
Conocephalus range from 10 to 27 mm in length, measured from head to wingtip. They can be distinguished from the related genus Orchelimum by being smaller and slimmer in general, the face usually being green and the ovipositors of females usually being straight.

The forewings vary in length. Some species always have short forewings, some usually have short forewings but occasionally have individuals with forewings longer than the abdomen, and some always have long forewings.

Species can be distinguished by the shapes of the cerci (males) and ovipositor (females).

Ecology
Bush crickets of this genus live in fields and meadows, where they feed on leaves, flowers, pollen and seeds of grasses and forbs. They also sometimes prey on other insects. Females lay their eggs in grass stems.
