Leafcurling midges distort shoots by rolling the edges of very young leaves, and the damage persists as the leaves mature. Early season damage can affect flower clusters, sometimes leading to fruit distortion. Leafcurling midge larvae and pupae can infect the calyx of fruit at harvest, where they spin cocoons.
