The red gum lerp psyllid is one of many psyllid species that attack eucalyptus. Two psyllids that feed on Eucalyptus were found for the first time in Florida in the spring of 2001 in tourist parks in the Orlando area: Glycaspis brimblecombei Moore, the red gum lerp psyllid, and Blastopsylla occidentalisTaylor, the eucalyptus psyllid. The insect is considered a serious pest that causes leaf discoloration, severe leaf drop, twig dieback and some tree mortality on some Eucalyptus species.
