description

butterfly

The wingspan of the moth is 28 to 34 millimeters. Compared to other Hoplodrina species, they have relatively long, elongated fore wings, the upper side of which shows a yellow-gray to light gray-brown basic color and irregular black scales. A few dark spots stand out from the front edge . Ring and kidney flaws are large, filled with dark and outlined in light. The outer transverse line is dark, jagged and mostly broken up into dots. The light wavy line is laid out dark. There is a row of very small arrow marks on the edge of the hem. The undersized upper side of the hind wing is whitish in color and somewhat darkened towards the hem.

egg

The egg is hemispherical in shape and initially light yellow, later dark in color. The surface is covered with strong longitudinal ribs, about half of which reach the micropyl zone .

Caterpillar

Adult caterpillars are yellowish-gray to reddish-gray in color. Back and side back lines are light and very thin. The entire body is covered with black point warts and short white hair bristles. The spiracles are black.

Doll

The red-brown doll has four hook bristles on the cremaster , of which the two middle ones are strong.

Similar species

The light brown dust owl ( Hoplodrina ambigua ) differs through shorter wings and less distinctive drawing elements. With Hoplodrina hesperica , the blemishes and the overall appearance are darker and the wavy line is almost straight. It occurs only in some regions of Spain and southern France, so that there is little geographical overlap with Hoplodrina superstes .

distribution and habitat

The yellow-gray rock-ground dust owl is widespread in Central and Southern Europe. In the north there is a population on Alderney . The moths sometimes reach the British mainland as migrant moths . The eastern extension extends to the Urals , the southern to Morocco , Turkey , Ukraine and northern Iran . The main habitat of the species are warm slopes and rocky valleys, abandoned vineyards, bushy heaths, semi-arid grasslands and dry forest edges.

Way of life

The nocturnal moths form two generations per year in some areas, which can be found in the north univoltin from June to July and in the south additionally from August to September. You are flying towards artificial light sources . The leaves of dandelion , plantain ( Plantago ), bedstraw ( Galium ) and dock species ( Rumex ) serve as food plants for the caterpillars . The caterpillars overwinter.

Danger

The yellow-gray rock-ground dust owl occurs in different numbers in the central and southern German federal states and is listed in category 3 ("endangered") on the red list of endangered species . In Baden-Württemberg it is on the "warning list".
