Minute scavenger beetle (likely a feather-winged beetle)

Leaf litter, compost, decaying vegetation, fungi, and other moist organic material; occasionally found indoors near damp areas.

Adults and larvae generally feed on fungal spores, mold, and decomposing organic matter rather than blood or living tissue.

Tiny, secretive beetles that crawl among organic debris and may disperse by flight; life cycles are associated with moist, decaying substrates.

Harmless to people, pets, clothing, and stored food in typical household encounters. They contribute to decomposition and fungal-spore turnover.
