Asian citrus psyllid (HLB vector)

Symptoms

Tiny (3–4 mm) brown-mottled psyllids that sit at a characteristic 30–45° head-down angle on new citrus shoots; nymphs produce curly white waxy tubules and honeydew on the flush; heavy feeding twists and stunts new leaves. Their importance is as the vector of citrus greening (HLB) rather than the direct feeding damage.
