Number of specimens and species as well as structure of aphidophagous communities in tree crowns of Douglas‐fir ( Pseudotsuga menziesii ) and Norway spruce ( Picea abies ) were studied in different forest stand types (Douglas‐fir‐, spruce‐ and beech‐dominated) in southern Germany in the year 2000, using flight‐interception traps. Total as well as average numbers of specimens and species of aphid predators were higher on Douglas‐fir in all stand types. This was particularly evident in Douglas‐fir‐dominated stand type. The aphidophagous community revealed a low β ‐diversity on spruce but a high β ‐diversity on Douglas‐fir between stand types. Both species, with a broad and narrow ecological niche, respectively, were responsible for a community on Douglas‐fir conspicuous different from that on spruce.
