features

butterfly

The wingspan of the moth is 24 to 34 millimeters. All wings are colored a rich green to green-gray. The green color elements can fade with increasing service life and then take on yellowish tints. On the front wings of two weakly corrugated white transverse lines can be seen, the outer continues on the rear wings. The hind wing edge shows a slightly protruding corner in the middle, above which there is an indentation. The fringes of all wings are very conspicuous, alternating white and reddish brown. The scientific name of the species is also derived from the Latin fimbria = fringe. The antennae are combed on both sides in both sexes, but only briefly in the females.

egg

The egg has a slim shape and tapers towards the bottom. In the upper quarter there are about twenty straight ribs. It is greenish at first and later turns carmine-red with yellowish spots to black-brown.

Caterpillar

Younger caterpillars usually have a light brown color that changes to greenish tones in adults. A red line to the back can often be seen. The head and prothorax each show two reddish tips. At the end of the abdomen there are also two often reddish tips.

Doll

The doll is yellow-white in color and shows a dark center line and brownish points. Dark veins stand out from the wing sheaths.

Similar species

The bush moth ( Hemithea aestivaria ) is somewhat smaller and gray-white and black-brown at the edge. The main distinguishing features are the clear corner in the middle of the hind wings without an indentation above and the wavy white transverse line, which shows an outwardly directed point.

Geographical distribution and occurrence

The distribution of the species extends over large parts of Europe (with the exception of the far north and some islands in the Mediterranean ) and further southeast to Turkey , Lebanon , the Caucasus , northern Iran and southern Siberia . In Central Asia the ssp. magnata resides. Data from East Asia refer to the sister species Thalera chlorosaria . In the Alps , the Apennines and the Balkan Mountains , the grasslands rise up to 1,400 meters each, in the Sierra Nevada up to 1,600 meters and in Northern Iran up to 3,100 meters. It can be found predominantly on poor grasslands , steppes, heaths and stony heaps.

Way of life

The moths usually fly univoltin from June to August. A second generation sometimes appears in the southern valleys of the Alps. They are nocturnal and fly to artificial light sources . The caterpillars feed on polyphag from the leaves of various plants, including: Yarrow ( Achillea millefolium ), Breckland Thyme ( thymus serpyllum ), Dyer's broom ( Genista tinctoria ), Field Wormwood ( Artemisia campestris ), heather ( Calluna vulgaris ) and real goldenrod ( Solidago virgaurea ). The species overwinters as a caterpillar.

Danger

The grassland green leaf moth occurs in different numbers in the German federal states and is listed as not endangered on the red list of endangered species .
