The small sloe hairstreak ( Satyrium acaciae ), also called Krüppelschlehen-hairstreak or acacia hairstreak , is a butterfly (day butterfly ) from the family of the blues (Lycaenidae).

description

The name comes from the old name of the sloe as "real acacia", the moth has nothing to do with the tree species known today as acacia . Above the wings are dark gray-brown with faint orange spots in the anal corner . The female is larger than the male, the orange spots are more pronounced. On the gray-brown underside of the wing, there is a white, broken line in the post- disk region , as well as an upwardly tapering orange submarginal band in which a small silver stain can be seen below the eponymous wing extension, the “tip”. In the disk and basal region there are no points or markings, only a faint, light gray scale. The small sloe hairstreak can be confused with other hairstreak butterflies , but the differences are clear and allow photographic evidence.

Flight time

Satyrium acaciae is single-brood , which means that it produces only one generation that flies from June to July.

habitat

Dry to very dry, warm locations with an abundance of cripple sloes. The species often occurs together with the sail butterfly ( Iphiclides podalirius ) and has similar claims. In particular, freshly shrubby grasslands are populated.

Way of life

The forage plant is the blackthorn ( Prunus spinosa ). The eggs overwinter covered with anus wool in the forked branches. The caterpillar eats the leaves and usually sits on the underside. As the petals fall off, it has grown up. When the spring leaves appear, the caterpillar pupates. The moths feed mainly on white flowers, e.g. B. on yarrow ( Achillea spec. ) And thyme ( Thymus spec. ).

distribution

Satyrium acaciae is widespread from Spain to southern Russia. In the north the species occurs up to 49 ° N , in Germany and Poland up to 51 ° N. In places, the species is endangered because the biotopes created by grazing are being overgrown or reforested.
