An illustrated Key to the larval stages of dipterous families in Egypt

Abstract

In Egypt order Diptera includes sixty-four families (steyskal, 1967), In addition to a new recorded family, Diopsidae (Stalked-eye flies). It is worth to mention here that, the larval stages act as an important role for determination and separation of the families and the species of order Diptera, particulary the unknown specimens of agriculture quarantine. Identification of dipterous families, within the scope of the present work, depends up on an illustrated key, for the first time, in Egypt.
