Dorsoventral pattern formation: Morphogenesis of longitudinal coloration in Graphosoma lineatum (Heteroptera: Pentatomidae)
- N/A
Postembryonic development of the adult color pattern of the shieldbug Graphosoma lineatum (organized as six symmetrical pairs of stripes parallel to body axis, i.e., with necessary dorsoventral positional information involved) was analysed and compared with patterns of some similar pentatomoids. All studied species, despite the probably different ecological role of their coloration (cryptic or aposematic), appear to display the same morphological regularities involved in their dorsal color pattern (three longitudinal pairs of stripes on pronotum and scutellum, more or less fused posteriorly and/or reduced). It is possible that a parallel origin of this color pattern reflects some general morphogenetic regularities whose models are discussed briefly in comparison with the well known situation in Drosophila.
