First I would like to Welcome you to ILGM as you can see there on it big time.
This will help you better understand them little buggers.
Leaf miners
These Little creatures are a pain to get rid of, the miners eat and dig squiggly lines into your leaves all the while planting there larvae in them making it hard to get rid of them. They plant there eggs in the leaves in mid When they hatch they feed off of your leaves untill they get big enough to pupate. Pupation occurs within the leaf or in the soil beneath the plant. After they emerge the entire cycle will start over and you will have a bigger infestation. You can tell you have leaf miners by looking at your leaves; it will look like someone carved scribble lines all over the plants leaves. Leaf miners also can leave your plant open to pathogens and fungus and low yields from the damage to the leaves. The females dig into the leaves and lay there eggs, the sap that is secreted when the leaf minors do damage attract ants and flies. . If your plants are affected during late flowering or close to harvest, please try to use the safest means of control to be safe to your health.
Controls
Controls: Natural control for these insects is difficult. You can remove affected leaves and discard them. Chemical control is hard and is ment towards the emerging adults. Since the larvae is well protected within the leaf. Neem oil will work well.
