Bionomics
Hibernates as an egg. The young larva bores into the fresh stem of the host plant and feeds on the inside. Often the top of the host plant droops or wilts. The caterpillar prepares an exit hole. Sometimes the covering piece of bark falls off before emergence.
Pupation inside the stem, just below the exit hole. The pupa does not protrude the exit hole before emergence.
The adults come to light and to sugar.
Flight periods
The adults fly in one generation a year; starting from mid-July till late October.
