Features
Butterfly
The relatively small moths reach a wingspan of 16-21 millimeters. On the wings pale yellowish tints prevail. Four narrow dark transverse bands stand out gray or brownish forth on the front wings. The hind wings color coordinated to the front wings and have three dark binding. Sometimes the males are strongly darkened brownish and show only a few drawing elements. The fringes are checkered brown and white. The antennae of the males are combed to the tips, those of the females are thready.
Caterpillar
Adults caterpillars have a green color and are characterized by thin white lines as well as back side colored wide side stripes.
Doll
The doll is yellow-brown, finely punctured and shows two divergent peaks at short cremaster
Similar Species
The moths of Narraga tessularia usually show an overall brighter yellow or white colored appearance and narrower transverse lines and reach a slightly smaller wingspan (12 to 18 millimeters). To uniquely determine a genitalmorphologische investigation is recommended.
A good discrimination ability provides the caterpillar stage, as N. Fasciolaria only the field wormwood (Artemisia campestris ) takes as fodder plants, while N. tessularia to beach wormwood (Artemisia maritima ) lives.
Geographical distribution and occurrence
The distribution area of Narraga Fasciolaria extends from the eastern areas of Central Europe via Central Asia and southern Russia to East Asia. From Hungary and Moravia is the ssp. Narraga Fasciolaria danubialis known. The species prefers sandy areas inhabited, Ödländereien and Gentiles.
Way of life
The moths are predominantly crepuscular and fly sometimes even during the day. They are two generations per year. The first emerges from overwintering pupae in May, the second after a development period of just two months from July. The caterpillars feed on the leaves of field wormwood (Artemisia campestris ). Pupation occurs in a cocoon in the soil.
Endangering
Narraga Fasciolaria is mainly to be found in Germany in the eastern states and is run on the Red List of endangered species in Category 2 ( high risk ).
