The culprit is Trionymus diminutus, a 4mm sap-feeding mealybug that breeds relentlessly when the weather is warm and isn't killed by winter frosts. It deposits a white, waxy substance at the base of the sheathed phormium leaves. A mild infestation is not a problem, but in excess the plants will suffer and could even die.
Smudges of white, waxy deposits appear at the base of phormium leaves, deposited by sap-feeding insects. The mealybug can cause loss of vigour in the plant and, in extreme cases, death.
