Orthoptera Species Online

The Orthoptera Species File (OSF) is a taxonomic database of the
world's orthopteroid insects. It contains full synonymic and taxonomic
information for over 25,000 species and genera (all taxa described
prior to 1998) of the Tettigonioidea (katydids and haglids),
Grylloidea (crickets), Acridomorpha (locusts and grasshoppers:
Acridoidea + Eumastacoidea + Trigonopterygoidea + Pneumoroidea +
Pamphagoidea), Tetrigoidea (pygmy grasshoppers), and Tridactyloidea
(sand crickets), as well as images and sounds for many species. A
database for the Gryllacridoidea will become available in the
future. This site also includes a searchable database of entomologists
working on the Orthoptera.

We hope that this site will ultimately become a global database of
information on the Orthoptera and related orders. We invite all
scientists to contribute relevant and related information to the
database, such as images and recordings of species, data on
distribution, ecology, and behavior. We also would like to
incorporate as well gene sequences and other data pertinent to studies
on systematics of the group. Although at this stage the database is
restricted to the taxonomy, soon it will include fields containing
other data.
