The eggs of this species are laid on the bark of a foodplant. The young Caterpillars when they hatch, bore horizontally into the the stem and then downwards to make a vertical tunnel in which they live. They cover the opening and surrounding stem with a bag of silk and wood fragments, and emerge nocturnally to feed on the bark under the bag. These caterpillars are off-white, with a dark brown hairy head, and a brown thorax. The back of each abdominal segment has two pale brown dashes, and each segment is creased.
The caterpillars have been recorded attacking plants in various genera in MYRTACEAE including
