Supplementary material 1 from: Hébert C, Laplante S, Fréchette M, Jobin L (2018) Anticosti Island: a hot spot for Neospondylis upiformis (Coleoptera: Cerambycidae) in eastern Canada? Biodiversity Data Journal 6: e25553. https://doi.org/10.3897/BDJ.6.e25553

Shows how seasonal cumulative degree-days on Anticosti Island follow that of Havre Saint-Pierre in May and of an average of Havre Saint-Pierre and Cap-des-Rosiers in June and July. Allows using proxies for 1993 and 1998 as we do not have complete data for Anticosti in these years.
