- Siona lineata lineata (Scopoli, 1763)
- Siona lineata oenotriensis (Staudinger, 1915)
This rather common species can be found throughout Europe. It is quite rare in United Kingdom. It is also present in the Amur and Ussuri Regions, southern Siberia, central Asia, Kazakhstan, Caucasus, Asia Minor and Russia.
The wingspan is 35–40 mm. Wings are white or cream colored with dusky veins in the upperside and black or dark brown veins on the underside. The underside of the wings usually shows also a blackish transverse stripe beyond the middle, very faint in the hindwings. Fresh butterflies are usually cream colored, but as they get older, the wings are becoming whiter. With the disappearance of the scales the black veins on the undersides become increasingly visible on the uppersides through the wings.
The head is small, with large and globose lateral eyes. Legs are long and slender. The males have a long slender abdomen with a curved upward end, while in the females the abdomen is stouter and not curved. The females are also smaller and with more angular wings. In the females the abdomen has three longitudinal black lines.
The moth flies during the day in one generation from the beginning of May to the end of June . The caterpillar feeds on various herbs, (Origanum majorana, Dactylis glomerata, Hypericum maculatum, Vicia species, Galium verum, Solidago virgaurea, Achillea millefolium, Tanacetum vulgare), and woody plants (Salix aurita, Viburnum opulus). The species overwinters as half-grown caterpillar and then pupates in a cocoon attached to a grass blade, or a plant stem.
