Psyllids (bottom) and the Notoncus ant responsible for honeydew collection. In winter the ants are less active but the jumping plant lice nymphs still produce copious amounts of honeydew. On the left you can see some sooty mould that thrives on psyllid honeydew and is detrimental to the health of the leaf. Kyogle, NSW.
