Dragonflies are insects which date back to before the days of the
dinosaurs. Over 300 million years ago dragonflies with wing spans of three quarters of a
metre flew in the sky above rivers and wetland. Today dragonflies and their smaller
relatives damselfies, can be found around many unpolluted aquatic fresh water habitats. In
Britain there are about 44 species. Most of these are resident although there are some
migratory species. They usually colonise slightly different niches or emerge at
different times of the year.
