The Orthoptera Species File (OSF) is a taxonomic database of the world’s Orthoptera (grasshoppers, locusts, katydids, crickets, and related insects) both living and fossil. It has full taxonomic and synonymic information for all taxa, with complete taxonomic references, images, sound recordings, and specimen records.
The core purpose of the OSF is to provide a resource that makes research on Orthoptera more efficient as well as to cover the needs of policy-makers, environmental managers and the wider public for a consistent and up-to-date classification of the world’s Orthoptera species.
It is open to contributions from anyone with specimen records and images.
With the cooperation of The Orthopterists' Society
Grants awarded for 2024 can be found here here
OSF lives in TaxonWorks, the new infrastructure that powers OSF. The interfaces of TaxonWorks include a wide range of additional filtering and reporting functionalities. Please contact us (ciglianofcnymunlpeduar; braunfcnymunlpeduar) if you need extended access to the data. Over time we expect this site to gradually mirror these extended functionalities of TaxonWorks.
Find out more on this new public version of OSF. Learn how to collaborate with the Orthoptera Species File project. Contact information, technical details, and more are available at About.
