Sinossi
The International Congress of Entomology holds symposia on insect life-cycles every four years. This book arose from papers contributed by most of the speakers at the latest symposium held in Vancouver, Canada, in July 1988. It provides a diverse array of studies on insect life-cycle evolution which can be broken down into three main levels of approach: comparisons of genetic variation and covariation underlying life-cycle traits; comparisons of variable phenotypes within and among populations of the same and/or related species; and comparisons of habitat-specific traits regardless of relatedness.
