Figure 4From: Comparative insights into questions of lepidopteran wing pattern homologyspalt expression in Bicyclus anynana larval and pupal wings. (A) sal is expressed in the future eyespot centers (arrowheads), in the late 5th instar larval hindwing discs (50×); (B) sal expression extends to the scale-building cells in a larger circular pattern around the densely packed cells of the eyespot focus, at 19 h after pupation (arrowheads point to focus and to scale-building cells) (200×).Back to article page
