Abstract:

The effect of honeydew density on arthropod community structure was investigated in the Nothofagus forest of Nelson Lakes National Park, New Zealand. Pitfall trapping revealed no community response to honeydew density, whereas sticky trapping showed the community composition of trunk-dwelling arthropods varied along a honeydew gradient. Mycetophilidae, Staphylinidae, Pteromalidae and Margarodidae were classified as high honeydew biased, while Diapriidae and Platygasteridae were non-honeydew biased. Arthropod distributions within a forest are not uniform, as a result of honeydew patchiness.
