HEMIPTERA, Naucoridae -- <Images>
& <Juveniles> This is a small family
of insects species of which are the
creeping water bugs.
Originally this family was placed in the Naucoroidea with the
Aphelocheiridae and Potamocoridae.They are similar in appearance and behavior
to the Belostomatidae, as they also occur in ponds and other quiet waters.
Sometimes, these insects also occur
found in damp places in dwellings, and are frequently believed to be
cockroaches. There are about 22 genera in 5 subfamilies, with worldwide
distribution. Their body shape that makes them
look like smaller Belostomatidae . They have raptorial forelegs for catching and holding their prey. Their small antennae located under the eye are often difficult to discern. Similar to the giant water Bugs they
have a cylindrical beak of 3 or 4 segments.
