Habitat

Obligate subcorticole found on a wide variety of trees, although some species seem to be favoured, especially Fagus sylvatica . In Sweden, however, the most frequent ‘host’ is Populus tremula ; in the Rhein-Main region of Germany, it is Alnus glutinosa . Common on Populus tremula in Belarus ( Tarasevich 1992). It may occasionally be found on the ground and has been taken in pitfall traps, even in grassland, perhaps during dispersal. It occurs in the southern taiga, broad-leaved and mixed forests as well as the northern forest-steppe.

Remarks

Parthenogenetic in the western, northern, eastern and southern parts of its large range, bisexual in the centre; areas of overlap where both forms occur are so far located in Denmark, the Netherlands, western Germany and Lithuania ( Enghoff 1976, 1994; Hoy Jensen et al. 2002).
