features

butterfly

With a wingspan of 33 to 40 millimeters, the species is one of the smaller owl butterflies. The narrow fore wings, which taper off at the apex, are striking . They have an ocher-colored, brown-white or reddish-gray basic color. They are often slightly dusty white-gray at the front edge. Striking is a dark welt that extends from the root field to almost the edge. The outer transverse line is formed by black dots. There are other small, black dots in the hem area. The hind wings are colored bright white or gray-white, whereby the veins stand out darker.

Caterpillar, pupa

The caterpillars are ivory in color, have an elongated shape and taper on both sides. On the back and sides, some weak, light, gray-edged longitudinal lines are visible. The black-brown, very slender doll has a rounded cremaster with two points and four bristles.

Similar species

There is a certain similarity to the narrow-winged reed owl ( Chilodes maritima ), which also has narrow forewings and an ocher-colored tint, but mostly shows two black points instead of the dark welt. In the somewhat smaller slanted-wing welted owl ( Simyra nervosa ), the longitudinal drawing is only weakly developed.

Geographical distribution and habitat

The welted reed owl has a Euro-Siberian distribution. It occurs from southern England to Japan , but is absent on the Iberian Peninsula , the Mediterranean islands, Greece, and central and southern Italy . The main habitat is coastal areas, reed-covered banks of rivers, ponds and lakes, as well as wet meadows, swamps and moors.

Way of life

In northern regions the species shows a univoltine behavior and the moths fly from May to June, further south there are also two generations per year. They are predominantly nocturnal and occasionally appear on artificial light sources or bait , the males are also active at dusk in warm weather. The main forage plant of the caterpillars is the reed ( Phragmites australis ). They pupate in the autumn in stubble or in folded reed leaves, where they also hibernate.

Danger

The species occurs in Germany predominantly in northern and central federal states, especially on the coasts of the North Sea and Baltic Sea to the island of Usedom . It is classified in category 3 (endangered) on the Red List of Threatened Species .
