The common blue damselfly is widespread and common. Adults can be seen from May to the end of August. It is a common species typical of lakes especially deep open sites. It has been recorded at greater altidtudes than most other damselflies.
Old English country names 'horse-stingers' and 'devil's darning needles' suggest that they were once feared. Neither dragonflies nor damselflies have the capacity to sting although they are predatory insects both in the larval and adult stages.
