The palps span Owl ( Polypogon tentacularia ), also Palpeneule , Small Palpeneule , shelled Zünslereule or fresh grass bush stockpile floor Zünslereule called, is a butterfly ( moth ) from the family of the cutworm (Erebidae). The species is both diurnal and nocturnal.
features
The male moths reach wingspans of up to 30 millimeters. The females are much smaller and usually a little darker in color. The forewings are yellowish brown to light brown and have three wavy to slightly jagged, dark brown transverse lines that can vary in strength. The line-shaped discoid line lies between the inner and outer transverse line. The hind wings are also light brown. In both sexes there are also quite light specimens. The palps are very elongated.
The caterpillars are light brown with a dark back line. The head is also dark brown.

Way of life
The species flies in one generation from early June to early August. An incomplete second generation can be trained in climatically favorable areas in August and September. The caterpillars appear from August. The main forage plants are hawkweed ( Hieracium pilosella ), presumably also narrow-leaved willowherb ( Epilobium angustifolium ) and bracken ( Pteridium aquilinum ). The rotting leaves of these plants probably serve as the main food. Pupation takes place in a cocoon on the ground. The pupa is relatively short and dark brown. The cremaster is rounded and has two small bristles. The pupa hibernates. The development into the butterfly sometimes only takes place in the year after next. The moths are attracted to the light. Nothing is known about a possible food intake of the moths.
Distribution and habitats
The species is widespread in Europe. It is absent on the British Isles and several Mediterranean islands. In northern Europe it occurs up to the Arctic Circle . In the east the distribution area extends over Russia to eastern China and Japan. The species lives on fresh and moist forest and mountain meadows, forest edges, roadsides, and fallow land on sandy soils. It occurs from the lowlands up to an altitude of over 1000 meters. While it occurs only sporadically in the lowlands and low mountain ranges of Germany, it has already been observed in large numbers in the Alps on mountain meadows at an altitude of 1000 meters.
