Trioza eugeniae

''Trioza eugeniae'' or the syzygium leaf psyllid, lillypilly psyllid, and eugenia psyllid is a sap-sucking hemipteran bug in the family ''Triozidae'' which creates galls on the leaves of ''Syzygium paniculatum''. This species is native to Australia and has been introduced into California.

The nymphs form pit galls in the leaves and stunt the plants growth.
