The Ziest silver owl ( Autographa pulchrina ), also known as the silver point humped owl , is a butterfly ( moth ) from the family of the owl butterflies (Noctuidae).

features

The Ziest silver owl is a medium-sized butterfly with a wingspan of 35 to 40 millimeters from the subfamily of gold owls (Plusiinae). The moths have purple-brown or copper-brown fore wings with silver-colored signs in the shape of a V with an adjacent point, which are sometimes connected to each other. In contrast to the very similar and slightly larger iota silver owl ( Autographa jota ), the drawing is more contrasting, more colorful and usually a little darker. The fringes on the underside are checked in black and white. The hind wings are brown-gray with a dark central band and dark border. The species varies widely in coloring and drawing, and the following forms have been described:

  • f.gammoides Speyer, with blackish-purple forewings
  • f.percontatrix Auriv., with merged metal characters
  • f. incipiens Schaw., ​​without metal mark

The caterpillars are green in color and have yellowish white, slightly wavy side stripes. The head is outlined in green and blackish. The doll is black.

Geographical distribution and habitat

The Ziest silver owl is widespread in Europe and is also found in parts of Siberia . In the Alps you can still find them at altitudes of over 1,600 meters. The occurrence includes sunny slopes, forest edges, riverside areas, meadow valleys, gardens and parklands.

Way of life

The females lay the eggs on the forage plant, from which the caterpillars hatch in autumn, which then feed on the leaves of a variety of plants, such as:

They overwinter and pupate mostly in May of the following year. The moths fly from June to August.

Danger

The species occurs widely in Germany in different frequencies and is therefore not classified as endangered.
