Remarks. The cases of Orthotrichia spp. larvae are usually described as ‘wheat or caraway seed’ shaped so that the cases of final instar Orthotrichia larvae are readily recognised. Only two cased larvae were collected in this study, which is not surprising, as usually the larvae in this genus are found in swiftly flowing waters, usually well attached to rocks, and possibly also to vegetation, as is likely in the many sandbed rivers in Angola. There are some records of larvae attached to Mollusc cases in lakes Kivu and Edward ( Jacquemart 1957).
