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.


Postdoctoral Fellow Joins the eButterfly Team

We are excited to have Dr. Federico Riva join us for a short fellowship. Over the next few months he will be working to map the distribution of North American butterflies, assessing trends in their populations, and helping to inform effective monitoring practices. We asked him to share a bit about his background and his work with butterflies. Welcome to the eButterfly team Dr. Riva!


eButterfly Taxonomy Updated

Months in the making, we’ve just made substantial improvements and corrections to the taxonomic backbone for eButterfly. This will drastically improve the user experience when entering checklists and exploring data. Learn about all the details…
