Hadena caesia is a butterfly ( moth ) fromthe owl butterfly family (Noctuidae).
features
butterfly
The wingspan of the moth is 32 to 37 millimeters. The color of the forewings varies from blue-gray to gray-brown and olive-gray to black-gray. Geographical influences are partly responsible for the color design. Occasionally some yellowish over-dusting can be seen. Blemishes and lines are indistinct and blurred. The midfield is slightly brighter. The hind wings are solid dark gray-brown.
Caterpillar
Adult caterpillars are reddish-gray to gray-brown in color, show an indistinct brown diamond mark on the back, a light back line, darker secondary lines and black point warts.
Similar species
- Hadena clara is distinguished by a yellowish spot that extends significantly in the middle field.
Geographical distribution and habitat
The species is locally distributed in Europe . The entire occurrence area is divided up like islands, which has led to the description of the following geographically isolated subspecies :
- ssp. caesia (Denis & Schiffermüller, 1775) in the Alpine region ,
- ssp. abruzzensis (Draudt, 1934) in the Apennine Mountains ,
- ssp. ostrogovichi (Hacker, 1989) in the Carpathian Mountains ,
- ssp. bulgarica (Boursin, 1959) in Bulgaria ,
- ssp. xanthophoba (Schawerda, 1922) on the Balkan Peninsula ,
- ssp. mananii (Gregson, 1866) in the British Isles ,
- ssp. frigida (Zetterstedt, 1839) in the southern part of Fennos Scandinavia ,
- ssp. grisea (Hospital, 1948) in the northern Spanish mountains,
- ssp. revolcadorensis (Calle, 1983) in the Spanish region of Murcia and
- ssp. castiliana (Reisser, 1935) in Castile .
The animals can be found mainly on stony meadows and slopes as well as in rocky valleys. In the Alps they rise to an altitude of 3000 meters.
Way of life
The moths are mostly nocturnal, fly from June to August and visit artificial light sources . When young, the caterpillars feed on the seed pods of nodding catchfly ( Silene nutans ), pigeon goiter ( Silene vulgaris ) and other Silene species, and later on their leaves. The species overwinters as a pupa .
Danger
Hadena caesia occurs in Germany in the Bavarian Alps and can be found in numerous regions there. The species is therefore classified as not endangered on the Red List of Threatened Species . Older information from Baden-Württemberg is probably based on false reports.
