The moths have a wingspan of 25 to 35 millimeters for the males and 28 to 29 millimeters for the females. The narrow front wings of the males have a dark brown to black-brown basic color. In the area of the middle field, an elongated yellow-brown stripe can be seen below the front edge. This is limited to the dark at the bottom. The apex is round. The females are drawn similarly, but the stripe is less contrasting. The basic color of their very narrow fore wings is light brownish, the apex is pointed. The hind wings of the males are large, unmarked and a single color gray-brown, those of the females are somewhat lighter and smaller. The antennae of the males are double combed.
Caterpillar
Adult caterpillars show drawing elements that are colored beige and red-violet. They are provided with small warts and strong bristles along the entire length of the body. The spiracles are black.
Geographical distribution and habitat
Stilbina olympica occurs locally in some areas in Greece , for example in the region around Olympia , the first place where the species was found, and prefers to populate mountain slopes and scrub areas overgrown with grass and herbs .
Way of life
The moths form one generation per year, whose main flight time is in September and October. The males sometimes fly in very large numbers towards artificial light sources . Since the females are almost flightless, they sit quietly on blades of grass. After fertilization, the eggs are scattered at random. The caterpillars feed on various grasses. From hackers were successful with perennial ryegrass ( Lolium perenne bred).
