A fairly common species throughout Belgium.
Native
The eggs are deposited in small, yellowish brown batches during May and June, they hatch in ca. 18 days.
The larva lives from July, hibernating, till April of the next year, 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.
The adults are active in early evening and later come to light. During daytime they are rarily seen. They use to fly rather high about trees at sunset.
One generation a year: from early May till the end of June.
Wooded areas, parks, forests.
