Box tree moth

Falter:

The moth reaches a wingspan of about 40 to 45 millimeters. The forewings are mostly silky white in color and have a broad brown band on the leading edge and the margin. A small, brown-colored bulge in the middle field and a crescent-shaped, white spot next to it are striking. The hind wings are also silky white and have a broad brown border. Occasionally, completely brown-colored specimens also appear, although the white spot is still present.

Caterpillar:

The caterpillars are up to five centimeters long, yellow-green to dark green and black and white striped, with black spots, white bristles and a black head capsule.
