Occurrence

The species can be found all over Europe, with the exception of Spain and Ireland . In the east, its distribution area extends through Russia and Asia Minor to China . The animals live in diverse areas, such as B. in birch moors , birch forests, heaths and parklands.

Way of life

The diurnal moths are difficult to recognize because of their small size, but you can find them when sucking nectar on the flowers of

They can also be lured with pheromone traps as bait .

Flight and caterpillar times

The moths fly from the end of May to the end of July, making them the first glass-winged species of spring alongside the alder . The caterpillars can be found from August to April of the next year.

Food of the caterpillars

The caterpillars prefer to feed on the wood of birch , alder or plums .

development

The females lay the eggs mainly on damaged or diseased parts of the tree. The development takes one to three years, depending on the climatic conditions, in Germany mostly one year. In the case of a two-year development, the hatched caterpillars feed on the border between healthy and dead wood in the first year. In the second year they create corridors about ten millimeters long and in autumn spin wood shavings into a solid cocoon in which they hibernate as a caterpillar. Pupation follows the following spring.
