Nymphs are found in a variety of freshwater habitats including lakes, ponds, wetlands, streams and rivers. Consequently, form one of the most important food sources for fish.

Flathead nymphs are most abundant and diverse in flowing waters of streams and rivers. groups, are presented. The family and respective sub­ families are morphologically redefined and their diagnosis reviewed. "evolutionary intermediate." The relative position of Pentagenia has served as a valuable phylogenetic landmark, and has made possible an understanding of the relationship of the Ephemeridae and Palingeniidae.

Mayflies spend almost the whole of their existence under water and in the nymphal stage. The majority of species prefer the fast-flowing or moderately fast-flowing type of waters, and so New Zealand, with its abundance of hill streams, is a particularly favourable country for their.

This book dealt with the microscopic life other than bacteria in fresh waters. It was a compilation of limnological data and methods for the study of aquatic organisms. Although this book was concerned primarily with drinking water, it did enter the field of the natural self-purification of streams, a subject more closely associated with sewage.
