Guide to the study of animal ecology

by Charles C. Adams

1879. Report upon Cotton Insects. U. S. Dept. Agr. pp. 511.

This report, like those of the U. S. Entomological Commission, gives very full accounts of the habits and life histories of certain species and gives particular attention to their predaceous and parasitic enemies. The predaceous insects are seldom given as detailed study as the vegetable-feeding kinds.
