Butterflies I've Seen allows you to keep track of all of your butterfly sightings.
Once your sightings are logged in the database, you can retrieve them by location, by date, or by species. You can print out a list of all the butterfly species you've ever seen, a "Life List," or you can print out a list of all the butterfly species you've ever seen at a particular location. At the same time, the sightings you enter provide important information that the North American Butterfly Association, the major butterfly conservation organization in North America, will use to help answer scientists' questions about butterfly distributions, abundance, and conservation.
Enjoy the site and the fact that your efforts are increasing our knowledge and helping butterfly conservation!
