Ohia Psyllid (several native Hawaiian species of the Family Psyllidae)
- Host: Ohia
- Distribution: Native to Hawaii
- Symptoms: Circular, conical, or convex galls on leaves, particularly new growth
- Management: Biological control by other native species (Sympiesis sp.) Because the ohia psyllids are native insects, avoid the use of pesticides as they or their parasites could become threatened or extinct.
