Vuoksinäin

Vuoksinäin is a genus of small, iridescent, often brightly colored beetles belonging to the family Staphylinidae. These rove beetles are typically found in damp environments, often in leaf litter, moss, or along the edges of water bodies. Their bodies are generally elongated and slender, with short elytra that expose several abdominal segments. The coloration of vuoksinäin beetles can vary widely, with many species exhibiting metallic greens, blues, coppers, or purples, which contribute to their common name, sometimes translating to "water jewels" or "shining water beetles" in various languages.

The habitat preference of vuoksinäin is a key characteristic. They are frequently observed in the littoral zones of lakes and streams, as well as in humid forests and bogs. Their association with water suggests a role in aquatic or semi-aquatic ecosystems, though specific ecological roles and life cycles are still under investigation for many species. Their diet is believed to consist of small invertebrates and organic matter found in their moist surroundings. Due to their small size and cryptic habits, vuoksinäin are often overlooked, making detailed studies challenging. Conservation efforts for these beetles are not typically prioritized individually but are often linked to the preservation of their sensitive wetland and forest habitats.
