A method of shaking was used to examine phytophagous and zoophagous bug populations living in the crowns of birch-trees and other forest species growing in an air-pollution area (Sneznk, North Bohemia). Elasmucha grisea (24.4%), Kleidoceris resedae (15%), Elasmostethus interstinctus (9.7%), and Lygocoris contaminatus (9.2percent) were dominant species among 71 bug species on birch. Crown fauna phenology indicated the most important activity of bugs in August and September. The activity of phytophagous bugs was dominant (68%).
