The first comprehensive inventory of dragonflies in the Parc national du Bic (Bic National Park, Québec, Canada) was conducted between 2021 and 2022. Fifty species were identified from 6 biotopes: a fast-flowing river, a recent pond in a restored exploited peatland, a shallow kettle lake, a salt marsh, a beaver pond, and a set of 4 small forest ponds. The discovery of an exuviae of the Twelve-spotted Skimmer (Libellula pulchella) in the park provided the first proof that this species can complete its development at this latitude. The update to the list of odonates occurring in the Bas-Saint-Laurent region added 38 species, bringing the total to 81. Global warming seems to have favoured the northward expansion of the Lance-tipped Darner (Aeshna constricta), the Dot-tailed Whiteface (Leucorrhinia intacta) and of the Common Whitetail (Plathemis lydia) in the province of Québec.
