Tentiform Leafminers
Tentiform Leafminer
(Phyllonorycter spp.)
Damage: Leafminer larvae create transparent blotches or serpentine line patterns on the underside of leaves. The leaf surface appears bubbled. Leafminers are rarely seen in blueberry fields.
Insect: Pale yellow caterpillars feed and tunnel between the layers of the leaf. Leafminer damage can occur throughout the summer.
