Most butterflies will become active or wake from hibernation during the first warm days of spring. However, emerging too early and facing unpredictable elements could be detrimental to the survival of the butterfly as they could encounter frost and harsher weather during consequent days of their short adult lives. According to new research from the University of British Columbia, the Université de Sherbrooke and the University of Ottawa, increasing temperatures caused by global climate change will ultimately affect the flight season timing of these winged beauties.
