"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 second half of 1999. This site also includes a searchable database of entomologists working on the Orthoptera."
