Excerpt from The Role of Insects in the Forest: From the Annual Report of the State Geologist of New Jersey for 1899
Exactly how much harm they do is perhaps a question. Their life history is not well known, and just how much living tissue the larva requires to bring it to the pupal stage is yet to be ascertained. It is reasonably certain, however, that they require two or more years to reach maturity, and that their presence alone does not indicate any serious danger to the trees.

Paperback. Zustand: New. Print on Demand. This book examines the little-known but important role that insects and other pests play in the life cycle of forests, with a focus on New Jersey forests. Beginning with a look at insect populations and their impact on individual trees, the author discusses pests that attack foliage, stems, twigs, and woody tissue, and explains how these pests impact the overall health of the forest. The book examines the role of woodpeckers and other birds as natural predators, and discusses the interplay of climate and insects in tree health. The author details the types of insects that feed on or in dead or dying wood, and the way in which their activity accelerates the decomposition of fallen trees and logs. This book is an important and timely resource for environmentalists, entomologists, foresters, and biology students.
