Owing to the heavy rainfall lots of pests and fungi are showing up. The latest to date are leaf miners, which are having a field day with many plants. Citrus trees seem to be attracting the leaf miners by the drove.
Leaf-mining insects feed on leaf tissue between the upper and lower epidermis. Leaf miners are slim, sap-sucking maggots of a small fly. They can sometimes be seen on leaves when examined closely.
