Species Composition of Leaf Beetle Assemblages in Deciduous ...

312 Bonner zoologische Beiträge 54 (2005)earlier, is that the environs of the trees have the decisiveeffect on the development of the species composition.Leaf beetles contribute a high proportion of the biodiversityof the deciduous tree canopy, sometimes occurringwith high species richness and abundance. However,the reasons for this occurrence and their potentialrole are poorly understood. Most of the species are certainlytourists, which arrived in the canopy by chance,since these tree species are not their food plant. However,it cannot be ruled out that some species may occasionallydraw moisture from the leaves of the deciduoustree species examined, especially if the main food planthas become inedible. With some species, consumptionof honeydew or sooty moulds is conceivable, althoughunsupported by observations specific to these species.Acknowledgements.
