larva, partly dissected out, and pupa
Not far above a node the leaf sheath is more or less swollen. Within the leaf sheath, in one or more elongated-oval depressions of the culm, each surrounded by a conspicuous rim, lies a white to golden, 4-5 mm long, larva. The shoot often is stunted.
The larva is described by Ertel (1975a).
