Figure 1. Morphological features of the pupae (A-C) and adults (D-F) of Ostrinia scapulalis. A and D: individuals generated by heat treatment. B and E: normal females. C and F: normal males. Sexually dimorphic mid-tibiae are indicated by arrows. Sexually dimorphic morphologies in the last abdominal segment are indicated by arrowheads. The pupa in panel (A) has male-like mid-tibiae and female-like abdominal morphology. Female adult wings are light cream while male adult wings are dark brown. The adult in panel (D) is male-like on its left wing but more female-like on its right wing. A mosaic pattern is also recognizable on the dorsal abdomen.
