Summary:

The spatial distribution and zonation of canopy-associated arthropods of the Acacia koa and Metrosideros tree communities that ran along an altitudinal transect on the southeast flank of Mauna Loa and Kilauea volcanoes in Hawaii, was determined by insecticidal fogging of the canopy with pyrethrum. Eight sites were samples on the Mauna Loa Transect where transect zones were determined on the basis of arthropod distribution. The influence of ecological factors, plant community structure, and climate were interpreted according to distribution patterns. As defined by other studies, the distribution of arthropod groups coincided closely with vascular plant communities of these transect. In order to further characterize the arthropod canopy-community, the composition, spatial distribution, and environmental relationships of the arthropod these communities, that occurred along the Mauna Loa Transect, were compared with the situation belonging to areas that were along other lower elevational transects to sea level in the Hawaii Volcanoes National Park as well as other ecosystems. Competition between ecological homologs, host specificity, vegetation structure, and climate appeared to have had the greatest influential significance on population density and spatial distribution patterns of the arthropod taxa that were studied.
