Common type of leaf mineworker include spinach leaf miners ( Pegomya hyoscyami ) , vegetable foliage miners ( Liriomyza sativae ) , and citrus leaf miners ( Phyllocnistis citrella ) .
Leaf Miner Life Cycle
The living round of a foliage mineworker starts as an egg that the distaff lays under the leaf ’s open . After seven to ten sidereal day , the eggs hatch into larvae and begin feeding on the leaf tissue paper .
