Citrus Leafminer

Citrus leafminers are tiny moths that lay their eggs on new citrus leaves. Upon hatching, the larvae work their way through the leaf, feeding, leaving a trail (also called a mine) that's visible as a squiggly line. The mines cause the leaf to curl, and on young trees, excessive feeding can retard growth. Worse, citrus leafminer damage allows for entry of bacterial citrus canker. However, there are parasitic wasps that help curb the leafminer population, and homeowners can spray new leaf growth with horticultural mineral oil sprays labeled for citrus as a preventative.
