The Grüngraugebänderte Rock Stone Spanner ( Charissa glaucinaria ), also Fettenhennen Stone Spanner called, is a butterfly ( moth ) from the family of the tensioner (Geometridae).
features
butterfly
The moths reach a wingspan of about 30 to 36 millimeters. They are extremely variable in their basic color. There are whitish, light-gray, yellow-gray, brown-gray, blue-gray or green-gray specimens. While the inner transverse line is usually only weakly developed on the forewings, the outer one stands out clearly from the ground and continues on the hind wings. All four wings have small, circular center spots, with those on the hind wings being weaker. The edge of the hind wings is clearly jagged.
egg
The egg is oval in shape and has longitudinal rows made up of small cells.
Caterpillar
Adult caterpillars have a light brown color, dark brown angular lines on the back and a whitish side stripe.
Doll
The doll is red-brown in color, stocky and equipped with two straight thorns on the conical cremaster .
Similar species
The most striking distinguishing feature to the very similar species Black Line Stone Spanner ( Charissa intermedia ) and Light Banded Stone Spanner ( Charissa pullata ) are the light-colored bands on the underside of the wings:
- In glaucinaria these are relatively broad, but blurred,
- in intermedia they are also broad, but very rich in contrast,
- with pullata the bandages are much narrower.
Subspecies
- Charissa glaucinaria fischeri
- Charissa glaucinaria glaucinaria
- Charissa glaucinaria intermediaria
- Charissa glaucinaria juravolans
- Charissa glaucinaria peruni
- Charissa glaucinaria salvatorensis
Geographical distribution and occurrence
The distribution area of the green-gray banded rock-stone spanner includes the mountains of Central and Southern Europe. The eastern occurrence extends to Turkey , Ukraine and Georgia . In the Alps , the species rises to over 2000 meters. It prefers to inhabit rocky valleys and gorges, mountain slopes and stony meadows.
Way of life
The green-gray banded rock-stone tensioner is a trivoltine type, i. H. up to three generations are formed per year, the moths of which fly in the months of May and June (first generation), July to September (second generation) and into November (third generation). The third generation appears only in the valleys of the Southern Alps. Only one generation develops each year above 1,300 meters. The moths are mainly nocturnal and fly to artificial light sources . During the day they like to rest on rocks and stones, from which they hardly stand out in color. The caterpillars live on various plants, for example on White Stonecrop ( Sedum album ) and at Campion - ( Silene ) and bluebells species ( Campanula ).
Danger
The green-gray banded rock-stone spanner is missing in the northern German federal states and is listed on the red list of endangered species as a type of warning list.
