title: Scanning electron microscope observations on third-instar Gasterophilus nasalis (Diptera: Oestridae).
abstract: Scanning electron microscope observations studied the morphology of 3rd-instar Gasterophilus nasalis (L.). Distinctive features are illustrated in a sequence of 16 micrographs, bearing indications of structures considered of special interest. The morphology of G. nasalis is compared with that of other larval bot flies.
