Description
The wingspan is 88–138 mm. It is similar to Marumba juvencus, but the lines of the forewing and the ground colour of the hindwing are more reddish and the lines on either side of the weak discal spot are hardly converge.

Biology
There are two generations per year with adults on wing in April and again in August in northern China. In Korea, adults are on wing from late May to late August.
The larvae have been recorded feeding on Castanea (including C. crenata), Castanopsis, Quercus (including Q. glauca, Q. mongolica, Q. acutissima, Q. myrsinaefolia, Q. acuta, Q. salicina and Q. serrata), Castanea crenata, Juglans (including J. regia and J. mandschurica), Lithocarpus (including L. edulis) and Eriobotrya species. Early instars are pale yellow, while later instars turn bluish green with the tubercles brown or reddish, tipped with white. Oblique stripes are formed of mauve or yellow tubercles on a white ground. The horn is green with paler tubercles.[3]
