Phytoncides play an important role in plant immunity and in the relationships between organisms within an ecosystem. [2] The ability to produce phytoncides is a quality common among plants.
Steelblue sawfly larvae are usually seen during the day in groups on the branches and stems of Eucalyptus trees. At night, they disperse to eat leaves of the host plants. When threatened, the larvae raise their heads and eject a strong-smelling, yellow-green liquid consisting predominantly of eucalyptus oil, to deter predators. [1]

Gonipterus platensis is a species of weevil in the family Curculionidae.It is commonly known as the eucalyptus snout beetle, the eucalyptus weevil or the gum tree weevil.It feeds and breeds on Eucalyptus trees and is endemic to Australia, though it is also found in New Zealand, North America, Hawaii, and western Europe.
Most species of Eucalyptus are trees, often mallees, and a few are shrubs. Along with several other genera in the tribe Eucalypteae, including Corymbia and Angophora, they are commonly known as eucalypts or "gum trees". Plants in the genus Eucalyptus have bark that is either smooth, fibrous, hard, or stringy and leaves that have oil glands.
Angophora is a genus of nine species of trees and shrubs in the myrtle family, Myrtaceae. Endemic to eastern Australia, they differ from other eucalypts in having juvenile and adult leaves arranged in opposite pairs, sepals reduced to projections on the edge of the floral cup, four or five overlapping, more or less round petals, and a papery or thin, woody, often strongly ribbed capsule.
