By Dennis M Forsythe, Emeritus Professor of Biology, The Citadel, Charleston, SC Other than a successful Carolina Butterfly Society sponsored weekend 2-3 June to the Francis Marion National Forest, butterfly numbers and diversity were very low across all of South Carolina during June-August. A Midlands Chapter CBS field trip scheduled for 25 June to the Enoree District, […]
By Rodrigo Solis On June 19th, 2015, five intrepid lepidopterists – Jacques Larrivée, Chris Schmidt, Rick Cavasin, Peter Hall and Max Larrivée – set out to explore the east side of James Bay in Quebec and identify the bogs to be monitored along a 10-degree latitudinal transect. Fast-forward to 2018, as pre-trip to the LepSoc meeting […]
Opportunistic data collection programs like e-Butterfly allow volunteers to report species observations from anywhere, and can quickly assemble large volumes of both historic and current data. But how valuable is the data? A new peer-reviewed study by researchers at the University of Ottawa used eButterfly data and a comparable dataset of professionally collected observations across Canada to […]
From July 28 to August 5, butterfly watchers across North America are invited to take part in the International Monarch Monitoring Blitz to help provide a valuable snapshot of Monarch population status across their late summer range. Participation is simple: find a milkweed patch and look for Monarchs, counting the number of stems you examined […]
Although they measure barely an inch across, the azures (in the genus Celastrina) cause a mile of consternation among lepidopterists. Even as these butterflies present sparks of blue, their taxonomy remains cloudy and controversial. I won’t resolve it for you here. Instead, I’ll tell you some of what we know or suspect about these blues, […]
Each year eButterfly keeps growing thanks to the dedication of many butterfly watchers and professional lepidopterists. In 2017 alone, 475 species were reported to eButterfly represented by nearly 12,000 checklists comprising almost 50,000 butterfly records and over 21,000 photographs. We now have recorded 741 butterfly species at over 35,000 locations across North America by nearly […]
Anyone who regularly submits to eButtery has come to understand our data quality process. It is of paramount importance at eButterfly. Typos happen, misidentifications happen, and well-intentioned eButterfly observers sometimes just make mistakes. All of us at Team eButterfly have done it, and we’ll do it again. Mistakes are part of surveying butterflies. Our team of volunteer […]
From a graduate school student’s lofty dream to a full-fledged citizen science program, eButterfly celebrates its 6th year with a new publication in a special issue of the journal Insects on butterfly conservation. The article – eButterfly: Leveraging Massive Online Citizen Science for Butterfly Conservation – highlights our accomplishments and outlines the bright future of […]
The endangered Quino Checkerspots (Euphydryas editha quino) are flying on the San Diego National Wildlife Refuge this spring for the first time in years. It selectively lays its eggs only on the Dwarf Plantain plant. Once found throughout California and into Mexico, the tiny Quino Checkerspot butterfly population is now extremely fragmented, which made it challenging for […]
In the northern part of North America, most butterfliers in the fall hang up their binoculars and cameras and head into semi-hibernation. However, more than a few simply head south in November to the Lower Rio Grande Valley in Texas. I have joined them from Ontario in the past two years and have been astounded […]
