The anise swallowtail butterfly, also called the yellow swallowtail or golden swallowtail, mainly harms umbelliferous vegetables such as fennel, carrot and coriander. Its larvae feed on the leaves, are active and feed at night, and when touched can extend an osmeterium from the thorax and secrete a foul liquid. The adult anise swallowtail butterfly has a yellow body, with a body length of 24-32 mm, and a black broad longitudinal stripe along the dorsal ridge; the forewings and hindwings have black and yellow markings, the hindwings have blue markings near the outer margin, and there is a red spot near the posterior margin. The egg is spherical. The mature larva has a body length of 52-55 mm, is green, has black longitudinal stripes on the head, and has short black transverse markings on the back of each thoracic and abdominal segment. The pupa is yellowish brown, striped, with 2 horn-like protrusions on the head.
The anise swallowtail butterfly has 2 generations each year, overwintering as pupae on thickets and tree branches, and emerges in April-May of the following spring. The first-generation larvae occur in May-June, and the adults emerge in June-July; the second-generation adults occur in July-August. Eggs are laid singly on the leaf surface. The larvae are active and feed at night, and when touched extend the osmeterium from the prothorax and secrete a foul liquid.
