features
butterfly
The relatively small moths reach a wingspan of 12 to 15 millimeters for the females and 15 to 18 millimeters for the males. Pale yellow-white tints predominate on the wings . Four narrow, dark transverse bands stand out gray or brownish on the forewings. According to Kasy , the basic color of the males of the populations of the Neusiedler See area is light yellow in the first generation, yellow-white or almost white in the second generation, and is always white in the female butterflies. The hind wings correspond in color to the forewings and have three narrow dark bands. The fringes are brown and white piebald. The antennae of the males are combed to the tips, those of the females are thread-shaped.
Similar species
The moths of Narraga fasciolaria usually show an overall darker yellow color as well as wider transverse lines and reach a slightly larger wingspan (16 to 21 millimeters) in both sexes. A genital morphological examination is recommended for a clear determination .
The caterpillar stage is a good way of differentiating it , as N. fasciolaria only accepts the field mugwort ( Artemisia campestris ) as a forage plant, while N. tessularia lives on beach mugwort ( Artemisia maritima ).
Geographical distribution and occurrence
The nominate form Narraga tessularia tessularia inhabits the Russian steppes . On the salt steppes in Hungary and in Burgenland the ssp. Narraga tessularia kasyi . Further occurrence areas are in Bulgaria , Romania and Slovakia .
Way of life
The moths are mainly crepuscular, but sometimes also fly during the day. They form two generations a year. The first appears from overwintering pupae from May, the second from July after a development time of only two months. The caterpillars feed on the leaves of the beach mugwort ( Artemisia maritima ). Pupation takes place in a cocoon on the ground.
