The results of a new study conducted by researcher Maxime Larrivée of the Montréal Space for Life Insectarium and his colleagues at McGill University and Université du Québec à Rimouski, demonstrate, with supporting evidence, that southern Québec up to Lake Saint-Pierre is now part of the ecological niche of the northern black widow spider (Latrodectus variolus).
