This is the British Dragonfly Society’s Dragonfly Discussion Group, a facebook group for dragonfly enthusiasts and professionals to discuss research topics and interesting observations.
The group is aimed at UK species, though observations need not necessarily have been made in Britain.
Example questions: the occurrence of blue colour form Southern Hawkers, and potential hybrids between Azure and Variable damselflies.
