Peltochares is a genus of aquatic beetles belonging to the family Hydrophilidae, commonly known as water scavenger beetles. It was first described by the French entomologist Étienne Mulsant in 1844. Members of this genus are typically found in Palearctic regions, inhabiting various freshwater environments.

Description and Habitat
Beetles in the genus Peltochares are generally small to medium-sized, typically ranging from a few millimeters in length. They possess an oval and somewhat convex body shape characteristic of many Hydrophilidae. Like other members of their family, they are primarily aquatic or semi-aquatic, commonly found in stagnant or slow-moving freshwater bodies such as ponds, ditches, marshes, and the vegetated margins of streams. They often inhabit areas rich in submerged vegetation, leaf litter, or decaying organic debris, where they act as scavengers, feeding on algae, decaying plant matter, and microorganisms. The larvae are also aquatic and typically predatory.
Distribution
The genus Peltochares has a predominantly Palearctic distribution. Species within this genus have been recorded across a wide range of territories including Europe, parts of Asia, and North Africa.
