Adults occur in standing or slow-flowing water, usually in vegetation over mud (Ref. 5723); found in streams, swamps and oxbow lakes (Ref. 10294). Feed on midge larvae and microcrustaceans, with isopods, amphipods, and mayfly nymphs important seasonally (Ref. 10294). Eggs are found attached to the substrate unguarded (Ref. 7043).
