Biology: 3-4 generations per year. They spend the winter in the form of a chrysalis and when spring arrives adults leave the fallen leaves during the autumn. They carry out the laying and 7-20 days the larvae that penetrate the leaf are born. At the end they make a cocoon and chrysalis inside the mine.

In biology and agriculture, leaf miners are larvae of insects that live inside the tissue of the leaves. Many of them cause damage to garden plants and crops.

Like woodworms, miners are difficult to control as they protect themselves from insecticidal sprays and plant defenses by feeding into the tissue of the leaves themselves, selectively eating only the layers that have the least amount of cellulose. When they attack the sessile oak they also selectively feed on the tissues that contain low levels of tannin, produced by the tree in great quantity as a defense.1 The precise pattern formed by the feeding tunnel is very often diagnostic of the class of insect responsible, sometimes even at the gender level. The mine generally contains depositions, and the pattern of these, the shape of the mine and the identity of the host plant are useful in determining the species of miner. The great majority of the leafminer insects are moths (Lepidoptera) and flies (Diptera), although some beetles and wasps also show this behavior. A few leafminer insects use other parts of the plant, such as the surface of a fruit.

METHODS OF FIGHT:

Alternative methods: placement of traps with pheromones.

Insecticide treatment in spring (the appearance of the first butterflies) with the active substances imidacloprid, deltamethrin.
