Larvae have a 2 year life cycle and 3 instars. Older larvae feed on underside of leaves at night.
Larvae 4.5 mm long. Brown head, prominent antenna, mandibles dark brown.
Body tapers at both ends; dark brown, lighter on underside. Shield has 10 hairs. Thorax has 8 hairs.
Thoracic legs brown. Al to A8 (and T2 and T3) ridged with one hair on ridge. Brown, wrinkled. 8 small prolegs.
