( Linnaeus , 1758)

The Black Hairstreak ( Satyrium pruni ) is a butterfly ( butterfly ) from the family of Gossamer (Lycaenidae). The specific epithet is derived from the plant species of the genus Prunus , whose leaves represent a food for the caterpillars .

features

On the upper side, the wings are dark gray-brown with a clear, upwardly tapering submarginal band , which extends over three veins in the male and to the fore wing in the female. On the gray-brown underside of the wing there is a white, broken line in the post-disk region , as well as a broad, orange, submarginal band with thick black dots that extends over the entire rear wing and a small silver stain below the eponymous wing extension, the "tip" see is. There are no points or marks in the disk and basal regions . The plum hairstreak can be confused with other hairstreak butterflies , but the differences are clear (especially the width of the bandage) and allow photographic evidence.

Flight time

Satyrium pruni is single-brood , that is, it produces only one generation that flies from mid-May to the end of July, depending on the location.

habitat

Warm sloe hedges and plum trees sheltered from the wind.

Way of life

The eggs overwinter in the forks of branches. The forage plant is mainly the blackthorn ( Prunus spinosa ). The caterpillar eats flower buds, flowers and later leaves. The moths like to suckle on common privet ( Ligustrum vulgare ), elderberry ( Sambucus ) and blackberry ( Rubus fruticosus ), so they seem to have a preference for white flowers.

distribution

Satyrium pruni is widespread from southern France to Siberia , Mongolia and Japan . In the north, the species occurs to southern Fennoscandinavia , with the exception of northern France. In places the species is endangered because hedges have been removed or are growing out.
