features

butterfly

With a wingspan of 17 to 22 millimeters or 14 to 22 millimeters, the moths are one of the smaller species of owl butterfly. The wings are short and wide, the front wings whitish or white-gray in color. The middle field usually stands out in a distinctive dark brown, with a narrow middle band sometimes appearing even darker. The post-fiscal region and the border area shimmer light brown. Ring, kidney and tenon flaws are missing or barely recognizable. The hind wings are solid white-gray and darkened at the edge. Male moths have combed antennae , while females have filiform antennae . The palps are light and noticeably long.

Caterpillar

Adult caterpillars are whitish, yellowish or brownish in color. They have two lines made up of black dots on their backs and small warts with long tufts of hair on each segment.

Geographical distribution and occurrence

The small blackberry bear occurs in Europe in the north to south of England and south of Sweden . It has been expanding northwards since the 19th century , for example to England in 1859, to Denmark in 1938, to Schleswig-Holstein in 1945 and to Gotland in 1949. The species is widespread in central and southern Europe. It is also proven in Asia to Japan . It prefers to colonize boggy swamp forests, hardwood floodplain forests, blueberry meadows and forest edges with blackberry scrub.

Way of life

The nocturnal moths fly mainly in June and July in one generation a year, in southern Europe a second generation sometimes appears. They like to visit artificial light sources . They rarely appear on the bait . In the typical resting position, the head is directed downwards. The caterpillars prefer to feed on the leaves of various blackberry species ( Rubus ), but also on other plants, for example blueberries ( Vaccinium myrtillus ), water mint ( Mentha aqualica ) or strawberries ( Fragaria ). The species overwinters as a caterpillar. Pupation takes place in a light web of dry blackberry branches.

Danger

The small blackberry bear occurs in all German federal states, but is on the red list of endangered species on the warning list. Since the species lives very hidden, this classification may not be mandatory.
