The aspen-hem ribbon tensioner ( Epione vespertaria , syn .: Epione paralellaria ) is a butterfly from the family of the tensioners (Geometridae), which is widespread in almost all of Europe .
features
The moths reach a wingspan of 25 to 30 millimeters. There is a big gender difference in terms of coloration. The males have a strong ocher yellow base color and have many small, red lines and a somewhat thicker red arched line on the fore and hind wings. This can also be present in females. A red-violet band goes from the front wing to the rear wing, this is a little wider in the male than in the female. The basic color of the females is pale yellow and the bandage is also paler than that of the males. The outer edge of the hind wings is usually irregularly wavy in females.
The caterpillar is brown, lightly striped, with reddish diamond spots on the back and a yellowish spot on the sixth segment.
Way of life
The species is rare and loves wetlands such as swamp edges and moist forest edges. The moths are nocturnal and fly from early June to late August. You can find them from the lowlands to the middle mountain regions. The caterpillars feed mainly on aspen ( Populus tremula ), but also on willow ( Salix ), birch ( Betula ) and alder ( Alnus ).
