Overview

Gyrinus aeratus is a species of whirligig beetle in the family Gyrinidae. It is found in North America and Europe.

Gyrinus aeratus, the lake whirligig beetle, faces severe population declines primarily due to habitat degradation and loss of suitable aquatic environments. Water pollution, eutrophication, and climate change impacts on freshwater ecosystems have significantly reduced the quality and availability of the clean, well-oxygenated lake habitats this species requires.
