Tettigoniids may be distinguished from the grasshopper by the length of their filamentousantennae, which may exceed their own body length, while grasshoppers' antennae are always relatively short and thickened.
The males of tettigoniids have sound-producing organs (via stridulation) located on the hind angles of their front wings. In some species females are also capable of stridulation. The males provide a nuptial gift for the females in the form of a spermatophylax, a body attached to the males' spermatophore and consumed by the female. The function of the spermatophylax is to increase the attachment time of the male's spermatophore and thereby increase his paternity.[3]
The eggs of tettigoniids are typically oval-shaped and laid in rows on the host plant.
