Brahmaea japonica  Adrian Hoskins
Introduction
The subfamily Brahmaeinae is elevated in rank to a full family by some authorities. It comprises of 7 genera and about 40 species. It has representatives in South America, Europe, the Oriental region and temperate Asia.
Brahmaea is the most well known genus, and comprises of 8 species - ardjoeno, certhia, hearseyi, ledereri, litserra, tancrei, wallichii and japonica.
Brahmaea japonica is found only in Japan.
Habitats
This species is found in humid deciduous forest.
Lifecycle
The eggs are pale brown, smooth and dome-shaped. They are laid in clusters of between 3-10 on the leaves of the foodplants which include Osmanthus, Ligustrum and Fraxinus ( Oleaceae ). During the early instars the caterpillar is white, marked with black and yellow. It has 4 very long wiry black filaments arising from the thoracic segments, and 3 more at the tail. In the final instar the filaments are lost and are replaced by short tubercles. The pupa is blackish. It is formed on the ground under stones or logs.
Adult behaviour
The adults are nocturnal, and rest during the daytime on tree trunks.
