Goal Help document butterfly distribution in Canada and the U.S.
Task Report butterfly sightings.
Where Canada
North America
United States of America

A real-time, online checklist and photo storage program, e-Butterfly is providing a new way for the butterfly community to report, organize and access information about butterflies in North America. Launched in 2011, e-Butterfly provides rich data sources for basic information on butterfly abundance, distribution, and phenology at a variety of spatial and temporal scales across North America.

e-Butterfly is maximizing the utility and accessibility of the vast numbers of butterfly observations, photographs, and collections made each year by recreational and professional butterfly enthusiasts. With your help, we will amass one of the largest and fastest growing insect data resources to inform our understanding of ecological and agricultural systems in North America.

Through time, each participant, each observation, each checklist, and each verification builds the database. eButterfly then shares this treasure trove of butterfly data with a global community of citizen scientists, educators, lepidopterists, conservationists, and land managers. In time, this information will become the foundation for a better understanding of butterfly distribution and population trends across North America and beyond.
