Bionomics
The larva feeds and tunnelling in the bark usually below a whorl of branches not higher than 2 metres. There it constructs a silk-lined gallery. Trees that grow in sunny places are preferred. They reveal their presence by throwing out yellowish to reddish drill dust. The full-grown larva hibernates and pupate in the larval habitation in a white silken cocoon.
During the day, they rest on the lower branches or trunk of the tree and becoming active after sunset. They come to light.
