Summary
We examined the movements of Chrysophtharta hectica, a eucalypt-feeding chrysomelid beetle in New South Wales, Australia, in relation to the beetle's sex, age and life-history, and to attributes of its Eucalyptus host plants. Beetle movements within the site were not influenced by beetle age or sex, but may be related to generation. Beetle distributions on the two host plant species, Eucalyptus stellulata and E. pauciflora, were generally clumped. Some of this clumping resulted from preference for E. stellulata over E. pauciflora. Clumping of beetles also occurred within host plant species; some plant individuals were consistently heavily used by beetles over the course of three years. We examined nutritional, spatial and biomass attributes of plants and found plant height and foliage production to be the best predictors of beetle numbers.
