Taxonomy of Aquatic Insect Nymphs and Larvæ

Nature volume 159, pages 595596 (03 May 1947) | Download Citation



ALMOST any collection of freshwater animals will contain a high proportion of insects in the larval or nymphal stage,and a number of these cannot, at present, be named with certainty. The work of many biologists, whether their interest be in ecology, physiology or the food of fish, is affected bythis gap in our knowledge, and the importance of closing it need not be stressed. It is the belief of the Freshwater Biological Association that, with sufficient co-operation from workers in other parts of the country, it should be possible, within a few years, to produce keys for the identificationof the aquatic stages of all the important groups, except the Diptera. The purpose of this article is to appeal for thisco-operation, to which end it includes brief notes on the existing systematic literature of the various groups and a short account of some of the methods of rearing adults from their nymphs or larvae.
