Development

Abstract

The information on the development of scuttle flies is scattered in the literature and is patchy in coverage. There is a need for more detailed comparative studies. Development within the egg is a largely unexplored field, but sometimes starts before the egg is laid (2.2, 2.4). Wolf and Blackman (1992) describe the ultrastructure of the developing gonads in the pupa of Megaselia Scalaris.

As the animals came to live in new (drastically different) environments . . . some of them managed to adapt themselves by changing their developmental timing, by either acceleration or retardation in the onset of development of structures (heterochrony) (Matsuda, 1987)
