Haplusia
Haplusia is a genus of gall midges and wood midges in the family Cecidomyiidae, established by Karsch in 1877. The genus contains more than 20 described species. These small flies belong to the subfamily Porricondylinae and tribe Diallactini. As cecidomyiids, they are associated with plant tissues, though specific ecological roles for most species remain poorly documented.
