Early heat and insect strike are stressing urban trees – even as canopy cover drops
But there’s more going on – insects are on the march. Many eucalypts are showing signs of lerp or psyllid attack. These insects hide underneath leaves and build little waxy houses for themselves. But as they feed on the sap, they can give the leaves a stressed, pinkish look. When they appear in numbers – as they are this year – they can defoliate a whole tree with a serious infestation.
