 Most other midge families are bloodsuckers, but it is not possible to generalise rigidly because of the vagueness of the term "midge".There is, for example, no objective basis for excluding the Psychodidae from the list, and some of them (or midge-like taxa commonly included in the family, such as "Phlebotomus") are blood-sucking pests and disease vectors.Most midges, apart from the gall midges (Cecidomyiidae), are aquatic during the larval stage.
