wingless expression in Bicyclus anynana larval and pupal wings. (A, B) Joint visualization of Wg (red) and En (green) in late 5th instar larval wing discs (50×); (A) Wg is present in the distal margin but not in the future eyespot centers in late 5th instar larval wing discs; (B) En is present in the future eyespot centers and in the posterior wing compartment; (C, D) Wg is present in the future eyespot centers at 12 h after pupation and its expression if coincident with that of En in the focus (large posterior forewing eyespot depicted) (100×); (E, F) Joint visualization of Wg and En at 16.5 h after pupation, while Wg levels (E) drop in the future eyespot centers, En (F) is still present in the future eyespot centers (50×); (G, H) Enlargement of 4th hindwing eyespot (200×). Arrowheads point to eyespot centers in all panels.
