What's the name of the green bug in front of the silkworm chrysalis?

The green bug in front of the silkworm chrysalis is tussah.

Tussah is a silking insect, named after its love of tussah leaves. Tussah is completely metamorphosed, and its larvae molt four times in the process of growth and development, from larva to pupa, and then from pupa to adult. The pupa of tussah is spindle-shaped and divided into three parts: head, chest and abdomen. The head is small with tentacles, compound eyes and mouthparts. There are 3 pairs of pectoral muscles and 3 pairs of pectoral muscles in the chest, which will be adult feet in the future. The abdomen has 10 nodes, and the ventral surface of the last node has 1 pairs of suckers, which can stand on the leaf surface.

In a word, the larvae and pupae of tussah are green. They feed on tussah leaves, form pupae and eventually become moths.
