This practical guide provides a vast wealth of knowledge for the Francophone naturalist. It allows the identification and study of dragonfly naiads, either as underwater nymphs, or as exuviae left by new adults. The proposed identification key, creative and generously illustrated, allows to differentiate with confidence the 52 Zygoptera and Anisoptera genera found in Quebec and adjacent regions.
