Eugenia Psyllids are sapsuckers that cause the leaves of Eugenia and Syzygium species (Lillipillies) to curl up and bubble.
Psyllids suck plant juices and excrete a sticky substance called honeydew on which black Sooty Mold grows. Severe infestations can cause major problems, though they usually occur when the plant is already stressed, often due to a lack of water.
High psyllid populations can reduce plant growth, cause leaves to distort, drop, become bumpy, or die back.
