Some Butterfly, Lepidoptera, and Entomology Sites
Butterflies and Moths of North America
Butterflies and Moths of North America is an ambitious effort to collect, store, and share species information and occurrence data.
iNaturalist.org - A Community for Naturalists

Vanessa Migration Project on iNaturalist.org
We now have a Vanessa Migration Project page on iNaturalist. org for reporting sightings of Red Admirals, Ladies, and other Vanessa species. If you often report observations to iNaturalist, or would like to post photos with your butterfly reports, our iNaturalist project page is another way for you to share your observations with us.
eButterfly is an international, data-driven project dedicated to butterfly biodiversity, conservation, and education. Report and track butterfly sightings, share your sightings and photos with others, and contribute to science and conservation.
