Insects and the Plant SurfaceBy Barrie Juniper and Sir Richard Southwood
Edward Arnold Ltd, 1986
Understanding how the surface of a plant affects an insects explains some insect behavior. The surface is a protective mechanism for the plant in various ways. As related to insects, it repels, attracts, and protects. It explains why some insects prefer undersides of leaves for ovipositing or why large leaves are more preferred; these are examples of the myriad of variables.

"In essence, the book is now a series of illustrated keys for identification. each key being preceded by supplementary information essential to its use. These keys, with a few exceptions. are easily followed by the nonspecialist and in most instances may lead the student to a generic identification, although frequently specific determinations can be made."
Rangeland Insect-Plant Associations on the Pawnee SiteBy Lavigne, R.J.
Annals of the Entomological Society of America 69(4), 753-763, 1976
This little article is a treasure for naturalists in grassland habitats of western North America, with a listing of observed plant-insect associations from a grassland site in Colorado. The listing is organized by plant species and separated into observations of insect species pollen and nectar feeding, consuming flowers, consuming leaves, etc. A good reference for anyone interested in relationships between insects and plant communities in the west, as a sort of baseline set of hypotheses regarding insects to look for associated with a given common plant species.
