common species throughout Belgium.
larva lives between two spun leaves into a tube on various trees and
shrubs. It hibernates full-fed inside that tube and also pupates in it.
Before pupating it closes both ends of the tube.
adults fly from early May till the end of June. They are active in
early evening and later come to light. During daytime they are rarily
seen. They use to fly rather high about trees.
