Aleocharinae

The Aleocharinae are one of the largest subfamilies of rove beetles, containing over 12,000 species. Previously subject to large-scale debate whether the subfamily deserved the familial status, it is now considered one of the largest subfamilies of rove beetles. The Aleocharinae are generally small to minute beetles, as they can reach a maximum length of about 10 mm (0.4 in), but usually they are 3–5 mm (0.12–0.20 in) long, with a few species of 1 mm (0.04 in), among the smallest of beetles. The body is usually slender, often densely and finely punctured; the head is more or less round and the color may be light or dark brown, reddish-brown, or black, sometimes with contrasting colors of red, yellow, and black.
