The buckthorn hairstreak ( Satyrium spini ), also known as the "sloe hairstreak", is a butterfly (day butterfly ) from the family of the blues (Lycaenidae).
description
Above the wings are dark gray-brown with faint orange spots in the anal corner . In females, the orange spots are more pronounced, an orange shimmer can be seen on the forewing. 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 large silver stain can be seen below the eponymous wing process, the "tip", which closes the submarginal band. In the disk and basal region there are no points or marks, only a faint, light gray scale. The acacia moth can be confused with other hairstreak butterflies , but the differences are clear (especially large silver stain) and permit photographic evidence.
Flight time
Satyrium spini is single-brood , ie it produces only one generation that flies from late May (southern locality ) to July / August.
habitat
Dry to very dry, hot locations with abundant occurrences of cripple sloes , which ideally stand above scree.
Way of life
The forage plant is the buckthorn ( Rhamnus ). The eggs overwinter in the forks of branches. The caterpillar eats the leaves and usually sits on the underside. The moths like to suckle on yellow-flowered ragwort species ( Senecio ).
distribution
Satyrium spini is common from the Iberian Peninsula to Iran and Iraq . In the north, the species occurs up to 54 ° N, with the exception of Belgium , northern France and the Netherlands . In some places the species is endangered, as the biotopes created by grazing are being overgrown or afforested.
