Comparison of wing primordia of a viviparous female (a) and an oviparous female (b) during embryogenesis. Transverse planes of thoracic segments are shown. Left and right panels show whole and magnified images, respectively. Although wing primordia are not observed in oviparous embryos (b), viviparous embryos possessed primordia after stage 18 (a). Arrowheads indicate wing buds.
