Main taxonomic characteristics of H. armigera and H. assulta . (A) (B) (C) and (D) show the phenotypes of the egg, larva, pupa and adult of H. armigera (left panel) and H. assulta (right panel). (E) The green dashed line shows that the two black hair-base and stigma are in a straight line on the prothorax of H. armigera (left panel); the green dashes show that the two black hair-base and stigma are not in a straight line on the prothorax of H. assulta (right panel). The read arrows show the stigma of the prothorax. (F) The proleg crochet is in double order for H. armigera (left panel) but in single order for H. assulta (right panel). (G) Two anal spines of the abdominal end are born on a large black protuberance for the pupae of H. armigera (left panel); the two anal spines of the abdominal end do not share the black protuberance in H. assulta (right panel). (H) Forewing without white stripes, and the outer edge of the hindwing with a wide brown belt of H. armigera (left panel); forewing with a white stripe, and the outer edge of the hindwing with a narrow brown belt of H. assulta (right panel).
