Naucoroidea

Naucoris cimicoides, from here.

Belongs within: Panheteroptera.

The Naucoroidea are a group of aquatic, predatory bugs with raptorial forelegs, spinose mid and hind tibiae, and lacking veins in the membrane of the hemelytron (if present) (Carver et al. 1991). Most breathe when submerged by carrying a bubble of air between the wings and the dorsum of the abdomen though members of the Aphelocheiridae are capable of plastron respiration (Richards & Davies 1977).

Characters (from Richards & Davies 1977, as Naucoridae): Small or medium, broadly oval, flattened insects; antennae four-segmented, simple; rostrum strong, three-segmented; membrane without veins; coxae hinged; fore legs usually strongly raptorial; hind legs fringed with swimming-hairs.
