Index

The pagination of this electronic edition does not match the edition from which it was created. To locate a specific passage, please use the search feature of your e-book reader.

Each species is listed under its English and scientific name; no distinction is made between entries for eggs, larvae or adults. A page reference may encompass more than one appearance of an item on a single page. Any entry qualified by a sex designation refers to the adult insect. Where a term is abbreviated in the text, the abbreviation follows the index entry for that term.

Prefixes to page numbers indicate the location of (B) boxes, (F) figures, (M) distribution maps, and T (tables).
