Citrus Leafminer (Phyllocnistis citrella)
Citrus leafminer (CLM) are small moths whose larvae consume leaf tissue between the epidermal layers of citrus leaves, leaving behind serpentine paths, or mines, in the leaves. This species is native to Asia but is now widespread throughout much of the global citrus production regions. It was first detected in Florida in 1993 and is established throughout the state.
CLM larval feeding has its most pronounced impact on young trees, causing damage to young leaves to the extent that it can impact photosynthesis and stunt tree growth if not managed. In addition to this direct damage, larval feeding within the leaf tissue also causes open wounds on leaves that make it easier for pathogens to enter. As such, their feeding damage often has canker lesions developing along the mine.
