Prophalangopsidae

The family Prophalangopsidae are insects belonging to the order Orthoptera. They are the only extant members of the superfamily Hagloidea. There is only one extant genus in North America, where they are known as grigs, four genera in Asia, and many extinct genera (see below).

The closest living relatives to the Prophalangopsidae are the family Tettigoniidae (katydids or bush-crickets), but the evolutionary split occurred more than 230 million years ago in the Permian.

The female of the species consumes the wings of the male during mating.

Haglidae is often used as a synonym of the family, but is used to refer to a distinct grouping of extinct hagloids by paleontologists.

Subfamilies and genera
The Orthoptera Species File lists the following: Archibald, Gu, and Mathewes (2022) removed the genera †Albertoilus and †Palaeorehnia from the family, moving them to a revised †Palaeorehniidae which they considered unplaced as to superfamily.
