Non-Native Invasive Dragonflies

Five non-native damselfly and eight non-native dragonfly species have been recorded in Britain as a result of accidental introductions, either as eggs or larvae in imported aquatic plants. Most have been found in the greenhouses of importers of tropical pondweeds. However, at least one species (Ischnura senegalensis) has been discovered at a garden pond, to which it was probably moved with recently imported pondweed. Although unlikely, there is a possibility that these or other dragonfly species could be encountered, particularly near commercial aquatic greenhouses. Some may also emerge from domestic indoor aquaria after sale. As the species concerned have originated in hot climates, it is unlikely – although not impossible – that successful establishment could occur in the wild, as happened with Oriental Scarlet (Crocothemis servilia, pictured right) in Florida, USA.
