Facultative air-breathing (Ref. 126274); Adults occur in quiet areas of streams, sloughs, swamps and other wetlands over mud and debris (Ref. 5723, 10294). Often found in dense vegetation. They can tolerate drought, low oxygen levels and extreme water temperature (Ref. 5723). Adults feed on aquatic insects, amphipods, isopods, and snails (Ref. 10294).
