In Ukraine, this species infests plants of the Rosaceae family. However, according to Akimov et al. (1993) it prefers areas with high humidity. Specimens are found only in the protected fragment of Volyzhyn forest in BSBR. Local air humidity is the highest in this part of the reserve which is the optimum condition for this species in Ukraine.
