If you want to identify a species that you already have, follow our step by step questions that include pictures to help you identify your species. Click on the picture that best matches your specimen, and you will be taken to further questions that will eventually identify your species.

Please remember that this field guide only contains non-native species, so your species might not be included, and our guide is certainly not exhaustive in this field. When you reach your species page, be sure to check that it has the other characteristics listed on its page.
