Midge, for one, is a type of small fly that belongs to the family Chironomidae. They are commonly known as 'non-biting midges' because they do not bite humans, but they can be a nuisance due to their swarming behavior. The term 'MIDGE' is also used to refer to a person who is very small in stature. The crossword solution 'BITER' is an appropriate description for this type of fly, as they do bite other animals such as birds and fish.
