The stippling effect seen on the upper surface of this strawberry leaf is caused by two-spotted spider mite feeding damage. When the mites pierce the epidermis of the leaf to extract the sap, the cells begin to collapse, forming a chlorotic region of the leaf.
What are the translucent spheres on the underside of the strawberry leaf?

The translucent spheres are spider mite eggs.
This week’s questions are from Tom Bilbo Ph.D., Assistant Professor, Research and Extension Specialist, Vegetable and Strawberry Entomology.
