Schematic phylogeny of Diptera with structures of E(spl)-C from examined species. Colour coding of bHLH genes follows Fig. 1 (bHLH-1, light blue; bHLH2, Dark blue; her, green). Red hexagons indicate mα, genes. Orange hexagons indicate m2 genes related to mα. Light brown heptagons represent m1 genes, dark brown hexagons m6 genes. Arrows indicate direction of transcription
