Abstract
Hemimetabolous insects present many problems to the descriptive embryologist. Unusual histological difficulties are engendered by the tough egg membranes and intractable yolk of hemimetabolous eggs. The rate of development of the eggs is relatively slow, often occupying many weeks (Table I). The embryonic rudiment, especially in the early stages of its development, is discouragingly small relative to the size of the yolk mass. Development is epimorphic, leading to hatching with all segments fully developed and functional, and the later stages of development exhibit considerable structural complexity. During development, the embryo usually performs elaborate movements within the space enclosed by the egg membranes, adopting a succession of different postures. Finally, development is specialized in ways which outrun the limitations of the classical germ layer theory.
