Adult caterpillars look very stocky and are brown in color. The back and side back lines are black and interrupted, the wide, black, uninterrupted side bands are lined with yellow.
Doll
The doll is slender, reddish-brown in color and shows two short diverging bristles on the conical cremaster .
Similar species
The also white colored hard hay spanner ( Siona lineata ) is much larger (35 to 45 millimeters wingspan) and has dark veins, especially on the back of the wing. This type also has thread-like feelers.
Geographical distribution and occurrence
Crocota niveata occurs in Austria in the Styrian - Carinthian - Salzburg Eastern Alps region and in parts of Romania . The species inhabits alpine meadows and mountainous areas, whereby altitudes between 1500 and 2200 meters are preferred.
Way of life
The moths are diurnal and like to rest under the leaves of blueberries ( Vaccinium myrtillus ). The main flight times are June and July. The caterpillars live polyphagous on low plants from late summer and overwinter.
Danger
The species is absent in the German federal states. Older information about finds in Baden-Württemberg is based on incorrect determinations.
