Trixagus

Trixagus is a genus of beetle belonging to the family Throscidae, commonly known as false click beetles. These beetles are relatively small, with most species measuring between 2 and 6 millimeters in length. They typically exhibit a dark, often reddish-brown or black, coloration and have a somewhat flattened, oval body shape. The antennae are characteristically serrated or saw-like.

Species within the Trixagus genus are found in various parts of the world, with a notable distribution across Europe, Asia, and North America. They are generally found in damp or humid environments, often inhabiting leaf litter, moss, or decaying wood. Their larvae are typically subterranean, feeding on the roots of plants or on decaying organic matter. The adult beetles are more commonly observed on the surface, though they are not frequently encountered due to their small size and cryptic habits.

Information regarding the specific life cycles and ecological roles of many Trixagus species remains limited. Their classification within the Throscidae family places them alongside other beetles that share a similar morphology and are sometimes confused with true click beetles (Elateridae) due to their ability to right themselves when overturned, though their mechanism differs. Further research is ongoing to better understand the diversity and ecological significance of this genus.
