Leaf miner is a term used to describe the larvae of many different species of insect which live in and eat the leaf tissue of plants. The vast majority of leaf-mining insects are moths (Lepidoptera), sawflies (Symphyta) and flies (Diptera), though some beetles and wasps also exhibit this behavior.

Identifying Features[edit]

From May onwards leaves may show the damage caused when the white grubs burrow inside, this later turns into blisters. Younger plants are more at risk.
