Eastern Monarch Population Increased

The presence of monarch butterflies in Mexico’s forests this past winter was 35% greater than the previous year, according to the most recent survey led by WWF Mexico. This increase marks a sign of recovery—albeit a fragile one—and gives some reason for hope against a backdrop of several decades of decline for the iconic species. According to the survey, Forest Area Occupied by the Colonies of Monarch Butterflies in Mexico During the 2021-2022 Overwintering Season, the species’ presence in and around Mexico’s famed Monarch Butterfly Biosphere Reserve grew from 5.19 acres in December 2020 to 7.02 acres in December 2021.


Inuk identifies new subspecies of butterfly while working with Montreal Insectarium

It was a cloudless midsummer day in 2019 when Siaja Parceaud-May noticed a Booth’s sulphur butterfly that had some “noticeable differences.” She was about an hour north of her home community of Kuujjuaq in Quebec’s Nunavik region with a team of entomologists and researchers from the Montreal Insectarium, learning how to identify and collect butterflies. Along a sandy, cleared ridge toward Ungava Bay, she spotted the peculiar critter that would be sent to Montreal for further analysis. Her hunch turned out to be right. More than a year later, insectarium director Maxim Larrivée wrote to her — confirming that she had discovered a new subspecies of Colias tyche. To her surprise, it would be named in her honour: Colias tyche siaja.


Parnassius iBook for our community

We are pleased to share a new iBook, “Wings that Make Waves”. Biological illustrator Kim Moss teamed up with Ecologist Dr. Diane Debinski and Ph.D. student Simone Durney to create this interactive book, which is focused on using butterflies as bioindicators. The authors wanted to make the story of their research more accessible to the general public, park visitors, and K-12 teachers.
