About Brahmaea japonica Butler, 1873
Brahmaea japonica has a wingspan ranging from 80 to 115 millimeters. Males are smaller than females of the species. Its wings are wide, with a rounded outer edge. The background color of the wings ranges from brown to black. The wing pattern consists of concentric alternating wavy light and dark lines on the root and distal half of the wings, plus a sinuous marginal border. This pattern is made up of a large number of light wavy lines. On the forewing, the M2 vein originates slightly below the R-Cu apex of the wing cell; the base of M2 is 3 to 5 times closer to the base of M1 than it is to M3. The antennae are pinnate, with 2 pairs of outgrowths on each antenna segment; in females, these outgrowths are much shorter. Caterpillars of Brahmaea japonica feed on plants from the genus Privet (Ligustrum), which belongs to the olive family (Oleaceae).
