(p.93) Chapter 9 Insects and Conifers
The World of Northern Evergreens

E. C. Pielou

Cornell University Press

This chapter first describes the insects found in coniferous trees. It focuses on pest insects because they are common and therefore much more likely to be encountered than rare species. Most of these insects belong to one of four orders: Coleoptera (beetles), Lepidoptera (moths and butterflies), Hymenoptera (sawflies), and Homoptera (bugs). Beetles form the largest of all insect orders: about 40 percent of all the world's insects are beetles. At present, the most serious forest pests in northern North America are bark beetles, which have destroyed immense tracts of forest in the west, including Alaska, where various species attack all the pines, all the spruces, Douglas-fir, and western hemlock. The final section considers two other animals of the forests that are so common and so inoffensive that they seldom attract attention: ants and woodlice (also known as sowbugs).
