This book is an up-to-date synopsis of aquatic dance flies (Clinocerinae and Hemerodromiinae), insects that have been studied for more than 200 years in Europe. Its publication comes about 80 years since the last summary report and follows a period when new scientific methods were applied to long-standing unresolved taxonomical, systematic problems. In a period of environmental change, it also provides information for habitat conservation. Keys for males of all species together with drawings of terminalia are given, although females must still be associated with active males. Keys to larvae and pupae are provided wherever possible. weiterlesen
