Schematic comparison of localised DV patterning system components in different insects. Embryos are arranged on a phylogenetic tree showing major holometabolan taxa with estimated ages of branching points shown in red (mya: million years ago). Drawings highlight the expression patterns of the principal DV system components in embryos of N. vitripennis, A. mellifera, T. castaneum, C. albipunctata, A. gambiae, and D. melanogaster. Embryos are shown laterally: anterior is to the left, dorsal is up. Red: PMad; blue: dpp; green: sog; pink: tkv; purple: tld
