Abstract: Windstorm on November 19, 2004 seriously affected Norway spruce (Picea abies) forests in Tatra Mountains, Northern Slovakia. We studied as to whether moth larvae and eggs overwintered successfully on branches of uprooted spruce trees. Also, we evaluated differences in assemblage structure of overwintering developmental stages of moths between the upper and middle crown area of wind-felled spruce trees. In May 2005, we sampled branches from a total of 12 wind-felled trees in Tichá dolina valley in the altitudes between 1,020 and 1,050 m. From each tree, a total of 30 branches were collected from both its upper and middle crown area. In addition, a total of 400 cones were sampled from the wind-felled trees. Moth larvae or hatched adults were obtained from branches or cones through photoeclectors in the laboratory. Larvae of one species developing in cones (Cydia strobilella), 3 species of bud-borers (Argyresthia glabratella, A. amiantella, A. bergiella), 7 needle spinning species (Batrachedra pinicolella, Chionodes electella, Syndemis musculana, Dichelia histrionana, Pseudohermenias abietana, Epinotia tedella, E. nanana), one free living species (Thera variata) and one species feeding on lichens or algae (fam. Psychidae
