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…
eButterflying Your 4th of July Count
The 4th of July Butterfly Count season is here! Each year, hundreds of butterfly enthusiasts participate in a cooperative effort to count butterflies within established 15-mile diameter survey circles. Most counts depend on the efforts of multiple parties, with each individual or team checking different parts of the survey circle, then combining their counts into a final count total. These tallies are then used to compare between years. The counts are an important and long-running survey that help understand changes in butterfly populations at large scales. Your checklists can also be important for eButterfly too!
New Feature Alert: Project Pages
Our new eButterfly Projects tool allows you to easily and quickly create a hub for your event, club, class, or organization. An eButterfly Project creates a space for you that pools observations of eButterfly users together. You can automatically include all of the checklists and observations that fit the places, taxa, users, or dates that you specify. Whether you’re starting a community science effort, creating a home for your user group, or running a butterfly bioblitz; eButterfly Projects is the new tool for you.
Watch Our Recorded Webinar and Learn How to eButterfly!
Every time butterfly watchers raise binoculars and cameras to record a butterfly sighting, they collect important data. Recording the number, date, and location of each and every butterfly, no matter how common or rare, may seem trivial, even repetitive— but this detailed information can be invaluable to science and conservation. Join Rodrigo Solis Sosa, our Human Network and Data Coordinator, as he explains how to use eButterfly in this recorded webinar from April 27.
New Feature Alert: User Profiles
Have you ever wondered who is helping to identify and verify your butterfly observations? Or maybe you wanted to learn more about someone that sees a lot of butterflies in your area? Now you can! We just released the first version or eButterfly user profiles. The profile page has a small image, the user level, stats, and their most recent photos. We’ll be adding more features in the future too. Click on any user name in eButterfly and view their profile. Fill out your profile so that others can learn about you too! Learn how…
Climate Generalist Butterflies Expected to be Winners Under Climate Change in Canada
Forecasting species responses to climate change is integral to the development of adaptive and practical conservation decisions. Butterflies are climate-constrained in at least two ways, as ectotherms, the climate has a defining role in dictating where butterflies can live. Additionally, a warming climate may have huge impacts on their host plant availability. These constraints could mean certain butterfly species may have to move north, or up in elevation, to stay within their preferred temperature range. Predicting how butterflies might respond to such temperature and host plant shifts could inform decisions involving conservation prioritization, species management, and natural resource management.
New eButterfly Updates Just in Time for Spring
We’re excited to announce some great improvements and new tools for eButterfly that we just released, with even more on the way. Our team has worked hard all winter to improve how the communications center operates, adding additional languages, upgrading the checklist submission process, improving the user experience for viewing checklists, updates that increase the performance of eButterfly, and many minor bug fixes.
A Giant Leap for a Butterfly in Vermont and Beyond
In 2010 when the largest butterfly in North America fluttered among Ardys Fisher’s flowers at the end of July, she knew it was something neat. Now, our study published in Frontiers in Ecology and Evolution this week shows an unusually rapid northward range shift by the Eastern Giant Swallowtail over the last two decades.
Dramatic Decline in Western Butterfly Populations Linked to Fall Warming
Western butterfly populations are declining at an estimated rate of 1.6% per year, according to a new report published this week in Science. The report looks at more than 450 butterfly species, including the western monarch, whose latest population count revealed a 99.9% decline since the 1980s.
2020 eButterfly Year in Review
From the first observation of 2020, a Gulf Fritillary nectaring on the Gulf coast of Florida submitted by Gary Leavens, to a Long-tailed Skipper nectaring at the end of December shared by mbspang, butterfly watchers added over 38,500 butterfly records to the ever growing eButterfly database of checklists. The reports fluttered in all summer long. We had more than 8,300 checklists with over 22,000 photographs comprising 523 species of butterflies reported during the year.
International Monarch Monitoring Blitz 2020
From July 24 to August 2, 2020, volunteers in Canada, Mexico and the United States helped monarch experts gain more information to enable better understanding of the distribution of the migratory monarch butterfly, an emblematic North American species. This year 520 volunteers across 68 states and provinces participated in the Blitz. They recorded 9,649 monarchs at various stages of their life cycle, from eggs to full-fledged butterflies. And together, they monitored 40,321 milkweed plants, the sole food source for monarch caterpillars.
Climate Change Could Cause Decline of some Alpine Butterfly Species
The long-term effects of climate change suggests that the butterfly effect is at work on butterflies in the alpine regions of North America, according to a new study by University of Alberta scientists—and the predictions don’t bode well. The researchers used climate change models to understand the effects of changing ecosystems on alpine butterflies in North America. The results show that alpine butterflies who have specialized diets, meaning that they feed on one or a few plants, are more vulnerable to climate change because of fluctuations in their food. On the other hand, butterflies that have diverse diets are less likely to be affected.
The Quest for My Biggest Butterfly Holy Grail – Jamaican Giant Swallowtail
‘Holy Grail’ butterflies are those rare, remote, hard-to-find, attractive species that linger in the imagination. For Peter Hall, the holiest of grails for many years, beginning in his childhood, was the Jamaican Giant Swallowtail (Papilio homerus). It was more like a myth than an actual species – seen by few and living in only two isolated and diminishing locations in the remoter rainforest of the Caribbean island, Jamaica.
eButterfly’s Commitment to Fostering Inclusivity and Racial Justice
United by our passion for butterflies, eButterfly is a community where we share observations, photographs, and expertise.

Ten Steps to Better Butterfly Photography (new camera optional)
Summer is here and many of us are eager to get out butterflying with our cameras to bring images home to share with our butterflying buddies. While I don’t fancy myself as an expert photographer, I sure love to photograph butterflies and other insects. I realized over time that many tricks I took for granted to approach butterflies were foreign to many naturalists especially those new to it. After sharing some tips on how to approach butterflies and better photograph them with friends and colleagues and seeing them come back with much improved results and more species than they use to find, I thought this might be helpful to share.

A Target on Your Back Is Useful
Life is hard, especially if you’re a butterfly. Always feels like there is a target on your back. Turns out some of those targets (AKA wing eyespots) are useful to deflect attacks away from the butterfly’s vulnerable head and body. Having eyespots allows butterflies to live longer and lay more eggs. Surprisingly this deflection hypothesis […]
