Length up to 16 mm, dirty white to pale brown in colour and a black head. The body becomes a chocolate brown colour as the larvae develops and white portions between each segment give a banded appearance. Stiff bristles can be seen on the underside of the last segment of mature larvae.


Elongated, white eggs are deposited on leaves. The eggs later become orangey in colour.
