Macaria brunneata

Forest Moor Spanner ♂ on Cow Parsley

The forest bog tensioner ( Macaria brunneata, formerly Itame brunneata or Itame fulvaria ) is a butterfly (moth ) from the family of the tensioner ( Geometridae ).

Description

The species has a wingspan of 25-30 millimeters. The wings are ocher yellow, dusted close to the males, brighter in the female. The male is indistinct on the top, marked the females, however, sharply and clearly. The forewings have four brownish spots on the front edge, from which spring from two to three, rarely more transverse lines. The hind wings have two to three times more or less verloschene transverse lines.

Dissemination

The forest bog tensioner is widespread across Eurasia to the Americas from Alaska to Newfoundland and south to New England, Michigan and Wyoming. In Central Europe the species occurs mainly in the uplands and the Alps and in bogs of the lowlands occasionally locally common, in other areas, particularly limestone areas, it is rather rare or absent regional completely.

Occurrence

The type flies from may and july, blueberry forests, bogs, forest pelts, pagans and clearings. In the Alps it reaches 2000 meters. The caterpillar lives on blueberries or bog bilberries, rarely also in pastures, especially goat willow and ear candy. In blueberry forests, the caterpillars may occasionally produce Kahlfrass. The egg overwinters. It is oval, pink with strong hexagonal wetting and small white warts on the corners. The violet- colored from green to caterpillar has significant side ridge lines. They pupate in the soil.
