The Byasa alcinous’s distribution area is quite extensive and includes China, the Korean Peninsula, and Japan. On the territory of Russia, the northernmost part of the range is located. Alcinous is found only in the southern part of the Primorsky Krai in Russia.

Byasa alcinous is preferring to settle in broad-leaved forests along the banks of rivers and lakes, where Aristolochia must necessarily grow.

Description of Byasa alcinous

Byasa alcinous is one of the most elegant butterflies. Its wingspan is small and rarely reaches 1 cm. Its wings are dark brown in males and lighter in females, with a coffee shade and pronounced black veins. The lower part of the wings is brighter in both sexes than the upper one. Rear wings have a series of half-moon spots along with the edge, females yellow and males orange. At the end of the wing, there are dark caudal growths, reaching 2 cm in length.

The body is dark, pubescent with hair, and the males have several red spots on the chest and abdomen.

Caterpillars have numerous outgrowths on the body, which end in red dots. Colour is made up of alternating brown and white areas.

The behavior of Byasa alcinous

During the season, two generations of butterflies appear, the first in May of overwintered dolls, the second in mid-July. Summer butterflies are slightly smaller than spring ones. Byasa alcinous fly perfectly, but most of the time they spend sitting: males in the crown of trees, females in the grass. It feeds on nectar of flowers of Aristolochia, honeysuckle, and cherry. Byasa alcinous has few natural enemies, as caterpillars and butterflies are poisonous, which is indicated by bright red and yellow spots in their color. After fertilization, the female lays individual eggs on the young shoots of the Alcinous , thus avoiding competition in food with caterpillars of other species.

Byasa alcinous caterpillars feed on leaves, leaving them with characteristic cellular holes. They pupate on the lower side of the ground and winter near the surface with fallen leaves.

The Byasa alcinous butterfly’s odor is described as musk. Its larvae eat leaves, leaving characteristic cellular holes. They pupate on the ground’s surface, and spend their winters near fallen leaves. It is best to avoid the Byasa alcinous when possible. The caterpillars are also poisonous. The insect is a great pest control option in the region.

Byasa alcinous is thought to be monochromatic, with pupae that are primarily yellow. However, the pupae of this species vary in color according to temperature, humidity, and host plants. High temperatures and high humidity induce yellow and brown diapause pupae, which are the most common type of the species. Despite the ambiguous morphology of B. alcinous, it is a fascinating butterfly that is worthy of a closer look.

The larvae of Parides (B.) alcinous are found in various regions of Japan, including the Ryukyu Islands. Byasa alcinous ssp. yakushimanus is known to live in Korea. Its life cycle is bivoltine and has two generations. In addition to its two generations, the adult males of this species emerge 7-10 days earlier than the pupae of other papilionid species.

The subspecies of P. (B.) alcinous have been separated based on their geographic distribution. The main Japanese Archipelago, the Korean Peninsula, and the southern Primorski Islands are the subspecies of B. alcinous, while the Ryukyu Island subspecies are confined to the Miyako Islands. In contrast, the yakushimanus is widely distributed throughout the country.
