About Leaf miner moths
- There are numerous species of leaf miner moths in the UK.
- Common species of leaf miner moths include the rose leaf miner, apple leaf miner, azalea leaf miner, leek moth and more recently the devastating horse-chestnut leaf miner.
- Adult moths lay their eggs on or within the leaves of the plants and trees.
- Their maggot-like larvae burrow through the leaf tissue causing distinctive damage.
- The majority of leaf miner adult moths tend to be small in size with dull markings and are often well camouflaged.
- Larvae feed for couple of weeks and then pupate normally within the leaves. Some drop out of the leaves onto the soil and pupate underground.
- There are often multiple generations produced each year.
- Leaf miner species can sometimes be identified by the patterning of their mines, the droppings and larvae within.
