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.

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.
