features

butterfly

The moths reach a wingspan of 34 to 44 millimeters. The forewings are usually light yellow and show a light brown central field, which is bounded by a dark brown, almost straight transverse line inwards and another dark brown, slightly curved transverse line outwards and which also has a large black center. At the hem there is a line made up of black dots. The apex is pointed. Occasionally there are also specimens that are either solid yellow or reddish brown or dark brown in color. The contrast intensity of the middle field is also very variable. The hind wings are laid out in the respective color of the forewings, but mostly a little lighter. Because of the completely stunted suction trunk , the scientific name of the species is derived from the Latin elinguis  = "without tongue". The antennae of the males are combed on both sides, those of the females are thread-shaped. The thorax is very hairy in both sexes.

egg

The egg is square, flattened on the top and bottom. It is white-gray in color and marbled in a pale olive brown.

Caterpillar

Adult caterpillars are brownish or yellowish in color. A dark brown line stands out on the back, which is expanded at the segment incisions. You can sometimes see a few dark spots or slashes on the sides. Two small, pointed warts on the eleventh segment are characteristic.

Doll

The doll is shiny red-brown in color and shows two long hook spikes and some curved bristles on the cremaster .

Similar species

The sloe ornamental spanner ( Crocallis tusciaria ) differs by the more strongly indented outer boundary transverse line of the middle field, see there for further distinguishing features.

Geographical distribution and habitat

The Helle Schmuckspanner occurs from Morocco all over Europe. To the east, the occurrence extends through Asia to Japan . The polar circle forms the northernmost limit. In the Alps it rises to an altitude of 1,600 meters. The species prefers mountainous terrain and can also be found on heaths, moors and forest clearings as well as in gardens.

Way of life

The moths that appear in a generation are nocturnal. The main flight time falls in the months of July and August. Isolated specimens were found in September or October. They like to visit artificial light sources . The caterpillars live polyphagous on the leaves of various plants from late summer , for example on willow - ( Salix ), oak - ( Quercus ), linden - ( Tilia ), prunus -, elm - ( Ulmus ), gorse - ( Genista ), hawthorn - ( Crataegus ) and honeysuckle ( Lonicera ) or bilberry ( Vaccinium myrtillus ). The caterpillar is said to occasionally eat the larvae of other butterfly species, such as those of the hawthorn owl ( Allophyes oxyacanthae ). This is why the species was sometimes referred to as "murder tensioner" in the past. The caterpillars overwinter and pupate in June of the following year.

Danger

The Helle Schmuckspanner occurs in all German federal states and is classified as not endangered on the Red List of Endangered Species .
