Lilac leaf miners

Disease Information

Lilac leaf miners

Symptoms and damage

Leaf miners are basically the larvae of a small moth species called Caloptiliasyringella. These pests bore tunnels between the leaf layers, thereby giving a blotched appearance to the leaves during the start of summer. Subsequently, lilac leaf miners turn over the leaves and feed on them externally. Eventually, the color of the affected leaves become brown, thereby giving a burnt appearance to the entire plant.


When the first sign of leaf miner assault becomes evident, you can soak the leaves with neem or a nicotine spray. However, when you notice the damage, it is already very late to take curative actions. Nevertheless, you should immediately remove the affected leaves and clear the area beneath the shrubs of all leaves and debris during the fall with a view to protect the plants from being infected again. In fact, the damage caused by lilac leaf miners is more aesthetic compared to physiological. S. vulgaris or the common lilac is most vulnerable to invasion by leaf miners.
