Raspberries: Leaves have a bronze or yellowish-white speckling on them (spider mites)

Leaf bronzing is characteristic of spider mite injury. Prolonged feeding reduces leaf photosynthesis.

Raspberry leaf with yellow and white mottling. Mottling is composed of very small, entirely-bleached sections of tissue with sharp transition to healthy green tissue. Mottling is most prominent along central and side veins.

Mites live underneath the leaves and produce webbing. They are difficult to see with the naked eye.
