Collections were made regularly from a substratum of rounded stones in the River Lune, England, by lifting the superficial stones and sweeping a net beneath them. Three species of Ecdyonurus emerge one after the other from May to October. Months elapse between emergence and the capture of larvae of the new generation in the R. Lune but elsewhere, when the species occur alone, larvae abound in every month. It is concluded that the life histories are similar in the various types of water-body but that, when more than one species is numerous, small larvae do not come to the upper layers of the substratum until larger larvae of another species have vacated them. |
