It is necessary to key out this species by examining the specimen under a microscope. Please add a comment to explain how you identified it.
Often around water during periods of egg laying by the females and at the hatching of adults.
Usually seen during spring and summer when males create mating swarms which people can find quite a nuisance even though adults do not bite or feed.
The larvae of chironomid midges are called 'bloodworms' and they live at the bottom of lakes and rivers. The pupa floats to the surface where the adult then hatches out. They are very vulnerable to predation at this stage and rising trout and other fish are often feeding on this species.
Very common species in Britain.
