The Orange Yellow serotine tensioner ( Agriopis aurantiaria ), also Orange Yellow winter moth called, is a butterfly ( moth ) from the family of the tensioner (Geometridae).
features
butterfly
There is a strong sexual dimorphism between the two sexes .
The males have normally developed wings, reach a wingspan of about 26 to 35 millimeters and show a dark golden-yellow or orange-yellow to light brown basic color on the forewings, which are also dusted with many black scales . Occasionally, there are specimens with large black spots around the edge. The middle field is bordered by dark transverse lines, the inner straight and the outer with an arc. The hind wings shimmer in the basic color of the forewings, but are always paler in color and also show two thin, dark transverse lines. The feelers are double saw-comb-like.
The flightless females have almost completely receded wings, a clumsy body shape that tapers at the end and a gray-brown color. The stub wings are gray in color with two black cross lines. There is also a similar sexual dimorphism in other species of moths, for example in the corner spot brush spinner ( Orgyia recens ).
Egg, caterpillar, pupa
The whitish egg is oval, flattened on the underside and provided with many ribs.
Adult caterpillars vary considerably in color. There are brown specimens with wide, dark side stripes as well as brown-spotted ones with light stigmas .
The doll is red-brown in color and has a forked tip on the cremaster .
Similar species
- The gray-yellow broad-winged species ( Agriopis margiaria ) differs through the paler gray-yellow basic color and the more curved outer transverse line. Since the moths of this species also live in spring, a seasonal overlap is excluded.
- In the case of the more brownish-colored Great Frostworm ( Erannis defoliaria ), the boundaries of the midfield are usually wider and more jagged.

Geographical distribution and occurrence
The orange-yellow broad wing spanner is widespread from Spain through Central Europe to Russia. In the south it can be found from the western Mediterranean area to the Black Sea region and the Caucasus . Its northern distribution extends to central Fennoscandinavia . The species can be found in many different places, including deciduous forests, orchards, gardens, parks and residential areas.
Way of life
The nocturnal moths form one generation a year and live mainly in October and November, sometimes well into December. The males like to visit artificial light sources , the females are usually found resting on the trunks of different trees. The caterpillars can be found from May to June. They live polyphagous on a wide variety of hardwood plants and low plants. These include willow ( Salix ), beech ( Fagus ), birch ( Betula ), oak ( Quercus ), elm ( Ulmus ), linden ( Tilia ) and blackthorn ( Prunus spinosa ), raspberry ( Rubus idaeus ) and bilberry ( Vaccinium myrtillus ) and many others. The egg is hibernating.
Danger
The orange-yellow broad-winged species is widespread in the German federal states and is listed as not endangered on the red list of endangered species .
