* * *

Any of various insect larvae that live and feed within a leaf, including caterpillars, sawfly larvae, beetle and weevil grubs, and dipteran maggots.

Most leaf-miner burrows or tunnels are either thin, winding, whitish trails or broad, whitish or brownish blotches. Though leaf miners do not usually cause injury, they mar the appearance of ornamental trees and shrubs. One method of control is to remove and burn infested leaves; spraying with nicotine solutions or dusting with insecticides is effective only when the adults are emerging.

▪ insect
      any of a number of insect larvae that live and feed within a leaf. Leaf miners include caterpillars (order Lepidoptera), sawfly larvae (order Hymenoptera), beetle and weevil grubs or larvae (order Coleoptera), and maggots (larvae) of true flies (order Diptera).

      Most leaf-miner burrows or tunnels are referred to as serpentine mines, consisting of thin, winding, whitish trails, or as blotch mines, which are broad and whitish or brownish in colour. Although leaf miners do not usually cause significant injury, they do mar the appearance of ornamental trees and shrubs. One method of control on garden plants is to remove and burn infested leaves.

      Insecticides are usually ineffective for management of leaf miners because of their protected habitat within the leaf.
