In Drosophila guttifera, the morphogen ACTS in proximity to existing physical landmarks such as the intersections of veins and cross veins on the wing.
Late in wing development, the Wingless morphogen is produced and diffuses through tissue where it prompts cells in certain areas of the wing to make pigment.
