title: Expression of engrailed in embryos of a beetle and five dipteran species with special reference to the terminal regions.
abstract: The engrailed expression in embryos of a beetle, four midges and a fly has been analysed with special reference to the terminal regions. In all six species the segmental expression pattern is very similar but variability occurs in the clypeolabrum, foregut and hindgut. In some cases, segmental engrailed expression seems to be extended into the hind- and/or foregut. The engrailed expression of these species is compared with published data from other insects.
