The spikes cohesive beef tensioner ( Ectropis crepuscularia ) is a moth from the family of the tensioner (Geometridae). Another common German name for this species is plum moth , but this name is actually synonymous with the sloe moth ( Angerona prunaria ).
Some authors count the blueberry spanner ( Ectropis bistortata ) as a synonym for the serrated bark spanners, but this thesis is controversial.
features
The gray to dirty-white wings are covered with brown to dark gray scales, but their coloration does not stand out as strongly from the basic color as in the otherwise very similar diamond-bark tensioner ( Peribatodes rhomboidaria ). Darker moths are also quite common. A slightly jagged, white wavy line, accompanied by a dark interior, continues from the forewings to the hindwings. The zigzag bark tensioner reaches a wingspan of 38 to 45 millimeters.
Subspecies
- Ectropis crepuscularia crepuscularia
- Ectropis crepuscularia abraxaria
Occurrence
In forests of all kinds, marshland, parks and gardens, the zigzag cortex can be found in northern and central Europe, but in the north it only occurs sporadically. Adult moths can be seen from March to September, they fly at night and are attracted by light.
distribution
The species is distributed from the British Isles through Central and Eastern Europe to East Asia. It also appears in North America . The southern limit of distribution is the western Mediterranean (with the Balkan countries), Asia Minor and the Caucasus (to Kazakhstan ). In the north, the distribution area ends at the level of the Arctic Circle .
nutrition
The gray caterpillars have a very varied diet, including deciduous and coniferous trees, shrubs and lower plants. They can be found from May to July and August to September.
Reproduction
There are two generations of the serrated cortex tensioner each year. The flight time of the first generation lasts from March to May, while the second flies from June to September. The second generation pupae overwinter. In very bad weather conditions or in unfavorable locations, there is only one generation per year.
