features
butterfly
The wingspan of the moth is 12 to 14 millimeters for the females and 14 to 18 millimeters for the males. The basic color of the wings mostly shows strong orange tones. There are two gray transverse lines on the fore and hind wings, which can vary in intensity and are often indistinct. The transverse lines on the underside of the wings, which also show blackish discal spots, can be seen more clearly. The edge of the hem stands out dark, the fringes are blackish.
Egg, caterpillar
The egg is elliptical in shape and covered with a dense polygonal network.
The clay-yellow or dark earth-colored caterpillars look stocky and taper towards the front, where there are also some transverse folds. Your light back line is framed in brown on both sides. The slightly wavy side back lines are also brown. The pale side stripes are very narrow. The spiracles are whitish and reveal a large brown spot under each of the second to sixth segments.
Similar species
The golden-yellow grass- fed dwarf species ( Idaea aureolaria ) as well as Idaea luteolaria and Cleta filacearia all differ from Idaea flaveolaria by their less pronounced orange or yellow color.
Geographical distribution and occurrence
Idaea flaveolaria is particularly found in the southern Alps . Local occurrences in the Apennines and in Spain require confirmation. The species is also found in Ukraine , Russia , Turkey , Transcaucasia and Iran . In the Central Alps, it rises to 1,800 meters. It prefers warm, dry slopes and lawns .
Way of life
The moths form a generation from June to August. They like to fly during the day, especially the males. The females are airborne. This is also due to the smaller wingspan. Various low plants serve as food plants for the polyphagous caterpillars. The caterpillars overwinter.
