Computer Vision: Keeping an Eye on eButterfly

eButterfly, in partnership with the Montreal Institute for Learning Algorithms (MILA), has created eButterflAI, an advanced image recognition algorithm that has learned to recognize the genus and species for most North American butterflies based on their location and image. The tool will soon be coming to eButterfly.org for everyone to use. Learn more…


Recorded Webinar: Using Community Science Data to Monitor Butterflies

Butterfly walks are not only a relaxing activity, but also an invaluable source of data for science. Join Dr. Federico Riva as he discusses the importance of the checklists recorded in eButterfly for his work: (i) the use of butterfly checklists to understand population changes and inform conservation practices; (ii) the importance of “imperfect detection” – our inability to see all butterflies when we are looking for them – and how we can maximize the number of butterflies that we see at a site; (iii) his current work with eButterfly, that leverages thousands of observations from community scientists to help understand regions of conservation priority across North America.
