Acasis viretata

This species occurs in many different habitats, including deciduous and mixed forests, rocky slopes and valleys, as well as bushy meadows, bogs and taiga areas.

The forewing is yellowish olive-green, in the middle with a broad, grey transverse band that has wavy inner and outer edges.

Along the outer edge of the wing there is a white band interrupted by small, black double spots, this is a characteristic feature.

The caterpillar is green, more or less tinged with pinkish; it has three interrupted pink lines on the back, the central one sometimes inclining to purple, and broken up into large wine-red to red heart-shaped spots; the head is brown, sometimes marked with purplish, and there are two tiny points on the last segment.

The larvae feed on a wide variety of plants, including Rhamnus frangula, Hedera helix, Ligustrum, Ilex aquifolium, Cornus sanguinea and Sorbus aucuparia [3]
