The Janthina - Bandeule ( Noctua janthina ) is a butterfly (moth ) from the family of cutworms ( Noctuidae ). The Janthina - Bandeule is one of three types of Janthina - species complex, where the independence of the species Noctua Noctua janthe and tertia so far has not been proved safe.

Features
The moths have a wingspan from 36 to 44 millimeters; the males are 36 to 39 millimeters on average slightly smaller than the females (39 to 44 millimeters ). The basic color is usually brown with violet tint or red in the southeast of the circulation area with salmon- red tint (especially in females ). Ring and kidney blemish margins are white. The underside of the forewing is black from the wing base to above the wavy line addition. The Saumfeld is light brown. The two meet each other at the Kosta perpendicular fields, rare black box ends in a line denticulate on the veins of time.
On the underside of the forewing the black middle is mostly about diffuse and without sharp boundary into the lighter Saumfeld. On the hindwing the black randliche binding is relatively wide. The inner edge of the conjunctiva leads usually oblique, rarely almost perpendicular to the front edge. Here the black squamation can last up to the base. This can go so far that only a black margined yellow spot remains.
The eggs are yellowish white.
The caterpillar is reddish gray to ocher- yellow or greenish gray to light greenish gray. The bright back line is relatively narrow. The back also contributes to the rear opening, U to V -shaped back spots. The 12th segment is provided with thick, black wedge spots. The bright side stripes are also limited towards the back, sharp dark. The relatively small head is brown and has black bow strokes on. The small, brown pronotum has a bright center line.
Puppeist brown to reddish brown in color. It has the cremaster two thorns.
Similar Species
The Janthe - Bandeule is not safe to be distinguished with the help of features of the upper wing of the Janthina - Bandeule. The black edge binding on the top of the rear wing is in N. janthe usually narrower. The inner edge of the edge binding encountered in this kind almost at right angles to the front edge. From there, draw only a few or no black scales towards the black scales on the wing base.
In adult caterpillar of Noctua janthina the U- to V -shaped drawing elements are on the back less clearly designed as janthe with N.. The younger caterpillars (L2 to L4) of N. janthina have on the 3rd to 5th segment in the middle of the back no dark stains, which are present in N. janthe crawler same stages.
Geographical distribution and habitat
The exact distribution is known so far only insufficiently. The species occurs in Central Europe from Eastern and South Eastern France and a spur in the Iberian peninsula into it, via Italy, the Alpine countries, the Balkan Peninsula, to the Ukraine and Belarus to the east, Denmark and southern Sweden in the north. In southern Russia there is a larger isolated occurrence. From Turkey, the distribution area pulls up in the Caucasus region and Iran, in the south to Israel. The species occurs up to an altitude of 2100 m above sea level before
Way of life
The Janthina - Bandeule forms one generation a year, fly the butterfly from late July to early September. The moths fly occasionally even in the late afternoon. They are mainly crepuscular and nocturnal and come to artificial light sources. Visit flowers and come to the bait. Eggs are laid in regular Situated on tree branches.
The caterpillars are generally found in September. The adult caterpillars feed during the night, during the day they rest hidden in the vicinity of the base. During the night, they climb like the caterpillars of other species Noctua often several meters high on saplings of trees (eg white poplar ) and on shrubs and perennials. Be Called:
- White poplar (Populus alba)
- Stinging nettle (Urtica dioica)
- Common spindle tree (Euonymus europaea)
- Red Honeysuckle ( Lonicera xylosteum )
- ? Dandelion ( Taraxacum officinale)
The caterpillars overwinter and pupate in May of the following year in a hole in the ground.
Endangering
The species is very common and not endangered in Germany.
