The moma alpium ( Moma Alpium ), sometimes referred to as Orioneule or Orion Owl called, is a butterfly ( moth ) from the family of cutworms (Noctuidae).
features
The moths reach a wingspan of 34 to 42 millimeters. The head and thorax are colored light green with black spots on the patagium and tegulae . The basic color of the forewings is celadon green . These are equipped with black spots, which are concentrated in the area of the basal line, middle shadow and wavy line and trace the transverse lines. In most specimens, the wavy line is continuously developed and lined with dark green on the outside. The inner and outer transverse lines, on the other hand, are only indicated by individual, irregular points. The kidney and ring flaws are usually well developed and black in color. The hind wings are gray and become darker towards the terms, with an indistinct transverse line and a clear discal spot. The underside roughly mirrors the ornamentation of the upper side, but is far less distinct. The outer hem is dotted in black.
The egg is yellowish and strongly flattened at the lower end (hemispherical). The surface is covered with thin, serrated longitudinal ribs. One or two sickle-shaped red spots are formed near the micropyle.
The basic color of the caterpillar is dark gray to almost black. The fourth, sixth and ninth segments each have a white or yellowish-white transverse bead. The remaining segments are provided with thinner, light brown transverse ridges. The back line is designed as a fine, mostly more or less interrupted double line. The secondary ridge lines are much wider, but also mostly more or less interrupted. There are usually several thin lines on the page. The caterpillars are very hairy. The whitish to reddish, long hairs stand in tufts on warts. The centrally sunk head is black, reddish brown to light brown.
The doll is rather stocky and shiny red-brown. The cremaster is flattened with very short, outwardly curved thorns arranged in a circle. The males have six thorns, the females four thorns.
Similar species
The celadon owl is very similar in color to the green oak owl ( Dichonia aprilina ). However, this does not fly until autumn, so that the flight times almost never overlap. However, the drawing of the forewings is clearly different. For example, the middle shadow is clearly defined, while the wavy line is usually only weakly drawn.
Geographical distribution and habitat
The celadon owl lives from the Iberian Peninsula and southern England in the west over large parts of Central Europe, the Balkan Peninsula, Asia Minor, Russia, Belarus, the Ukraine, the Caucasus region through Siberia to the Far East ( Russian Far East , North China, Japan, Korea). In the north the distribution area extends to southern Scandinavia and central Finland. In the south it extends to northern Spain and northern Portugal, northern Italy ( reaching far south in the Apennines ) and northern Greece. The species is widespread, but not really common anywhere. It prefers deciduous and mixed forests, moors and parklands. In the Alps it occurs up to an altitude of about 1000 meters.
Way of life
The celadon owl forms one generation a year, whose moths fly from May to early August. They are nocturnal and fly to artificial light sources. Occasionally they are also observed on the bait . The caterpillars can be found from June to September on the leaves of English oak ( Quercus robur ), but also other types of alder ( Alnus ), birch ( Betula ), hazel ( Corylus ), hornbeam ( Carpinus ), poplar ( Populus ), whitebeam ( Sorbus ), Prunus (syn. Cerasus ) and Hawthorns ( Crataegus ). Pupation takes place in a firm web.
The pupa overwinters and often lingers for several years.
Danger
The celadon owl is a kind of advance warning in Germany. However, the risk situation looks quite different in the individual federal states. It is either missing or extinct in Hamburg. It is considered endangered in Lower Saxony and North Rhine-Westphalia, while it is endangered in Brandenburg, Mecklenburg-Western Pomerania, Saxony and Saxony-Anhalt.
