The Donaciinae are a subfamily of the leaf beetles, or Chrysomelidae, characterised by distinctly long antennae.

[3] Female Donaciinae lay eggs between aquatic plant stems and leaf sheaths.

[4] When larvae hatch they are aquatic, and attach themselves to underwater stems and roots of their plant hosts, primarily Potamogeton, for food and oxygen.

[5] Adults live in vegetation bordering ponds, marshes, lakes,[1] and brackish water environments.

[4] These six genera belong to the subfamily Donaciinae: Data sources: i = ITIS,[7] c = Catalogue of Life,[8] g = GBIF,[9] b = Bugguide.net[1]
