FAMILY GROUP STAPHYLINOIDEA

FAMILY HYDRAENIDAE

This family has about 1200 described species worldwide. Just a few species have been described from Southeast Asia but countless species are waiting for description. Hydraenids are small beetles that feed on algae in a variety of aquatic, riparian and littoral habitats, including springs, streams, waterfalls, wet rock faces, ponds and puddles. Outside Southeast Asia this group has also been recorded from marine rock pools, inland salt lakes and seabird nests.

Singapore Hydraenidae cannot be identified with certainty and our assignment to sp.1 – sp.3 is tentative and operational.
