The value of chorionic structure and size in the diagnosis of blowfly eggs.

Chorionic structure and size can be of great value in the identification of the eggs of British blowflies of forensic importance. The most useful features are the shape and structure of the plastronic area between the hatching pleats. Correct identification of the eggs of the species considered here would be of use in forensic investigations, not only in Britain, but also in the wide area of the Holarctic region.
