Leaf-mining is a habit employed by several insect, mainly the larvae of some flies, moths and beetles. The pattern of these mines relate to particular species of leaf miner. These leaf tunnellings can be comprised of straight or meandering lines, circular or in irregular blothes. They often feed on the section of the leaf between the top and bottom of the leaf surface. If a mined leaf is held up to the light the larva can often be seen in the tunnel. Leaf miner pests can affect a wide variety of plants including chrysanthemums, beet, celery, leek, delphinium and pyracantha.
