Invasive species image galleries are valuable tools for identifying and comparing invasive species and suspected invasive species. Use the search tool below to look for image galleries for particular species or groups of species (like weeds). For searches using species scientific and common names, put the name in quotes like this "Eriocheir sinensis" or "Chinese Mitten Crab".

* If you know about invasive species image galleries that you think should be included in this list, please contact Annie Simpson (asimpson@usgs.gov) or Elizabeth Sellers (esellers@usgs.gov).
