Acronicta auricoma
Gold hair moth ( Acronicta auricoma )
The gold hair moth ( Acronicta auricoma ), also Busch Gentiles moth is called a butterfly (moth ) from the family of cutworms ( Noctuidae ).
Features
The moths reach a wingspan of 34-39 millimeters. The forewings vary in color from light gray to dark gray. Root line and tornaler line are very much developed, the median stripe along vein A1 segment is relatively short. Most sits ventral to the tornalen stroke a white dot. The inner and outer transverse line is jagged and simply drawn black or merely indicated by dots. The outer transverse line is angled sharply between the tornalen line and the dorsum and jumps inwards sharply. The middle shade is usually well developed. The hem line is indicated only by a very small black dots. The ring flaw in most instances relatively large margins elliptical and black and with a central black dot. The kidneys blemish is also black margins with a larger black dot in the middle. The fringes are pale gray with narrow interneuralen strokes. The underside of the forewing is gray, the other hand held the underside of the hind wings a little brighter. The lower sides of the front and hind wings have a not very clearly developed outer transverse line on the hind wings additionally a Diskalfleck. Head and thorax are light gray to dark gray.
The egg is strongly flattened and conical. The surface has sharp longitudinal ribs. It is hellkarminrot colored, with yellowish spots and a dunkelkarminroten annular strip.
The caterpillars have a black ground color and numerous arranged in transverse rows on each segment orange warts point from which shorter at the top, orange hair on the sides and long, light hair spring. The head is shiny black.
The black- brown colored doll has a blunt cremaster, which is covered with short, straight spine -like bristles.
Geographical distribution and habitat
The gold hair moth is widespread in Europe. Even the Iberian Peninsula it is absent only in the extreme south. On the Apennine peninsula their occurrence is essentially limited to the Alps and the Apennines to the level of Calabria. On the Balkan Peninsula the distribution extends to the extreme north of Greece with smaller isolated occurrence in Central Greece. It is also missing on most Mediterranean islands, with the exception of the Balearic Islands. In northern Scandinavia, the gold hair moth happens even to the Arctic Circle. The former occurrence in southern England has gone out since 1912. However, moths were her ever since, probably immigrated found there. It is unclear whether an earlier occurrence in Southern Ireland still exists. In the east, the distribution area of Russia, Siberia extends into the Russian Far East, in the south of Asia Minor, Cyprus, the Caucasus, northern Iran, northern Iraq and Afghanistan to Central Asia.
The animals live along forest edges, in open woods and in bushes, in bog and heath areas, forest steppes and in parks; natural gardens and checked cultivated land. In the mountains, it rises to 2000 m above sea level.
Way of life
The gold hair moth is in the north of its range a generation in the South two generations per year. In Baden- Württemberg two generations in almost all regions formed only in the high altitudes of the Black Forest, the second generation is formed much weaker and could thus reflect incomplete second generation. The moths of the first generation fly regionally slightly different from mid-April to early June, the. 's Second-generation mid- July to September The beginning of flight of the moths may be delayed at higher elevations until mid-May. The moths are nocturnal and visit flowers ( Chrysanthemum vulgare observed on ), but also the bait. They also come to artificial light sources.
Caterpillars are then found from June; depending on the region the caterpillars until October or November at the latest have pupated and go into hibernation.
The caterpillars feed on polyphagous from the leaves of many deciduous trees and shrubs, mainly of willow ( Salix) and birch (Betula ), but also of poplar (Populus ), hornbeam (Carpinus ), alder ( Alnus ), beech (Fagus ), hawthorns ( Crataegus ), roses ( Rosa ) and Prunus. Ebert et al. (1997) lead in addition to about 20 species of herbaceous plant species; of which only the genres are called: Vogelknöteriche ( Polygonum ), sorrel ( Rumex ), Rubus, meadowsweet ( Filipendula ), sainfoin ( Onobrychis ), vetches (Vicia ), spurge ( Euphorbia ), blueberry ( Vaccinium ), heather ( Calluna ), loosestrife ( Lysimachia ), privet ( Ligustrum ), sage (Salvia ), oregano (Origanum ), thyme (Thymus ), mints (Mentha ), Knapweed (Centaurea ), scabious ( knautia ), Greis herbs ( Senecio ), thistles ( Cirsium ) and? Pestwurzen ( Petasites ).
Pupation takes place in a light brown cocoon, the pupa overwinters.
Endangering
The gold hair moth is currently classified as not at risk in Germany. However, the way in many areas seems to be rare.
System
Acronicta auricoma is of Fibiger et al. (2009) in the subgenus Viminia Chapman, assigned to 1890, together with Acronicta menyanthidis ( Esper, 1789), Acronicta orientalis man, 1862, Acronicta rumicis ( Linnaeus, 1758), Acronicta euphorbiae ( Denis & Schiffer Müller, 1775) and Acronicta cinerea ( Hufnagel, 1766 ). Subspecies are not distinguished. There are numerous synonyms.
