Learn How to use eButterfly: Join an Upcoming Live Webinar or Watch One Recorded!

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 one of our upcoming webinars and learn more about using eButterfly!


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. We also share a deep conviction that our collective experiences and observations will ultimately make the world a better place for butterflies, people, and the environment we inhabit together.

Pursuing Butterfly Holy Grails

For every butterflier, I would be willing to bet that over the years, when out on field trips, you have had some ‘special’ butterflies in mind that you hope to come across – in other words, ‘Holy Grails’ or, simply, grails.
