Dsx expression during wing development in Bicyclus anynana. Dsx expression during three different wing developmental stages, that is, midfifth instar, wandering stage and 28 h after pupation are shown for (A) male and (B) female forewings and (C) male and (D) female hindwings. The adult wings are shown in the first column and an expanded view of the scent organ regions in both sexes is shown in the last column. Images shown are the best, illustrative images and numbers at the bottom left indicate sample size. White and red dotted lines denote homologous veins in the respective wings and the orange and yellow dots in (C) correspond to the base of hair-pencils as in figure 1. Yellow arrowheads in (A) and (C) indicate the two scent patches on the forewing and hindwing, respectively and the red arrows in (C) indicate the secretory cells at the center of the patch. Scale bars are shown for the pupal wings and adult structures.
