Abstract
Four invasive eucalypt-feeding insects, native to Australia, are recorded from Gibraltar for the first time: the gall-forming wasps Ophelimus maskelli (Ashmead) and Leptocybe invasa Fisher & La Salle (Hymenoptera: Eulophidae), the lerp-forming psyllid Glycaspis brimblecombei Moore (Hemiptera: Aphalaridae), and the bronze bug Thaumastocoris peregrinus Carpintero & Dellapé (Hemiptera: Thaumastocoridae), whilst the status of two Eucalyptus longhorned borers, Phoracantha recurva Newman and P. semipunctata (Fabricius) (Coleoptera: Cerambycidae), is summarised. The former five species have been found on the red-gum tree Eucalyptus camaldulensis Dehnh., growing in the urban environment in Gibraltar. The potential impact of these invasive species is discussed.
