The Phasmida Species File (PSF) is a taxonomic database of the world's Phasmida (stick and leaf insects, known as walking sticks and walking leaves in the U.S.), excluding fossil species. There is full synonymic and taxonomic information for more than 3,500 valid species [+187 subspecies], 45,000 citations to 3,500 references, 8,600 specimen records and 20,900 images of 84% of valid species, with more being added to on a regular basis.

To see information contained in the database, use the links across the top of the page.  Click on Search to find a specific taxon or other kinds of information.  Clicking on Taxa will make the order Phasmida your current taxon unless you have previously moved to a different taxon in this session.

This website and database use Species File Software.  Information about the design and use of SFS may be found on a separate website.
