Preparation of a brown earth owl

The brown earth owl ( Diarsia brunnea ), also called brown herbaceous owl or red-fringed earth owl , is a butterfly ( moth ) from the family of owls (Noctuidae).

features

butterfly

The moths reach a wingspan of 36 to 45 millimeters. With regard to the color design, they do not show any great variability. The forewings are strongly reddish-brown in color and partly with a purple coating. There is a large black spot between the ring and kidney flaws. While the ring flaws appear in the basic color, the kidney flaws often show yellowish tones. The cone flaws are reduced to small black dots . Cross and wavy lines are usually indistinct. The fringing area is slightly brightened. The hind wings are light brown-gray without drawing.

Egg, caterpillar, pupa

The egg is spherical, flattened at the base, thinly ribbed and colored ash gray. The caterpillars are tinted dark brown, have whitish colored back, side back and side lines as well as dark slashes. On the eleventh segment there is a characteristic, thick, yellow-white line across the back. The red-brown doll is characterized by two longer, curved and four shorter thorns on the cremaster .

Similar species

There is a certain resemblance to the primrose earth owl ( Diarsia mendica ), although yellow-brown or light red-brown tones predominate. The plantain owl ( Diarsia rubi ), the moor meadow owl ( Diarsia dahlii ) as well as Diarsia florida and Diarsia guadarramensis are all drawn with less contrast, they lack purple tones and the butterflies are smaller.

Geographical distribution and habitat

The species occurs in almost all of Europe. To the east the distribution extends to central and southern China as well as to Japan. East Asian individuals belong to the ssp. urupina . The primrose earth owl prefers to inhabit deciduous, mixed and coniferous forests, heathland areas, raised bogs and parklands.

Way of life

The nocturnal moths mainly fly from June to August in one generation per year. You will visit artificial light sources and bait , and occasionally the flowers of the common bird cherry ( Prunus padus ), the flutter rush ( Juncus effusus ) or the dwarf elder ( Sambucus ebulus ). The caterpillars can be found from September. They feed on a wide variety of plants, for example:

Raspberry - ( Rubus ), nettle - ( Urtica ), willow - ( Salix ), birch - ( Betula ), dock - ( Rumex ) and chickweed species ( Stellaria ). They overwinter and pupate in a cave in May of the following year.

Danger

The brown earth owl occurs in large numbers in all federal states in Germany and is listed as not endangered on the red list of endangered species .
