A common species throughout Belgium.
Native
Bright green with 5–6 whitish, sloping crosslines. A prominent hook almost as long as the body width. When the caterpillar is full-grown, it looses its colourful pattern and becomes dull grey with whitish dots.
The caterpillar leaves the tree when it is full-grown and pupates in the earth.
The adults are active at night and come to light.
One generation a year from mid-April till well in July. Occasionally specimens have been observed during August and September.
