The Herbst- Zackenrandspanner ( Ennomos autumnaria ), sometimes also called Herbstlaubspanner , is a butterfly ( moth ) from the family of the Spanner (Geometridae). The specific epithet is derived from the Latin word autumnus meaning "autumnal" and refers to the time of flight of the moth.

features

butterfly

The moths reach a wingspan of 41 to 47 millimeters for the males and 47 to 52 millimeters for the females. The upper sides of the wings are colored ocher-yellow to yellow-orange and covered with brownish to violet-gray speckles. The middle field of the forewings is bounded by two dark transverse lines that approach each other at the inner edge . The wing edges are jagged irregularly. The antennae of the males are strong double-comb-toothed, those of the females are very short double-serrated. A proboscis is missing.

Pre-imaginal stages

The egg is barrel-shaped, angular and initially colored purple-brown or olive-green. Just before the caterpillars hatch , it takes on a chocolate brown color with a white edge. The micropyle is black, the microphyl rosette 11 to 15 leaves.

The caterpillars are very slender and essentially bark brown. On the fifth, sixth and ninth segments, wart-like bumps and on the eleventh, two short tips stand out. The head is large and dotted with dark brown. In the overall impression, the caterpillars look like a broken branch and are therefore hardly visible to predators.

The pupae are greenish to yellowish and slightly frosted. The cremaster is wrinkled and has several black hook bristles at the end.

Similar species

The similarly colored jagged edge spanner species oak jagged edge spanner ( Ennomos quercinaria ), ash jagged edge spanner ( Ennomos fuscantaria ), birch jagged edge spanner , ( Ennomos erosaria ) and alder jagged edge spanner ( Ennomos alniaria ) all show no or only slight speckles on the upper wing sides are smaller.

distribution and habitat

The autumn jagged edge spanner is widespread in Europe and temperate Asia as far as Japan . In Korea living subspecies Ennomos autumnaria koreennomos in Tianmu Mountain and Chekiang Ennomos autumnaria pyrosticta and in northern China Ennomos autumnaria sinica . The main habitat are deciduous forests and parks. The moths have even been found in the city center of large cities. This suggests that the caterpillars like to feed on the leaves of linden ( Tilia ), which can be found in city parks and on avenues. The common name "Lindenparkland-Zackenrandspanner", which is occasionally used, can be traced back to this. In the Alps , the species rises to around 600 meters.

Way of life

The moths are mostly nocturnal and fly in one generation between August and October. They appear at night in artificial light sources . In their resting position, they usually bend their wings at an angle. The eggs are deposited in extensive ice mirrors on branches or leaves and overwinter. The caterpillars live between May and June of the following year and feed on the leaves of various hardwoods, including linden ( Tilia ), birch ( Betula ), oak ( Quercus ), alder ( Alnus ), willow ( Salix ) and prunus .
