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!
