Donacia is a large genus of aquatic leaf beetles in the subfamily Donaciinae. Adults are active, capable of sustained flight, and possess adaptations for both aerial and submerged existence. The genus is distinguished by a truncate elytral apex and a pubescent area above the procoxa. Larvae develop on submerged portions of aquatic plants, while adults inhabit surface parts of the same host vegetation. The genus contains approximately 113 described species arranged into 15 proposed subgenera, with major radiations in the Nearctic and Palaearctic regions.
