When Is Leaf Miners Active ?  

Leaf miners are nothing but larvae of various types of insects. They can feed within the leaves, and as a result, they make a lot of holes in the leaf. This activity is very similar to mining activity, and that is why these grubs are called leaf miners.

There are hundreds of varieties of leaf miners in the world. There are so many insect larvae that have the same habit of feeding, and all leaf miners follow the same pattern and cause similar damage to plants. Moths, beetles, flies and insects fall under the category of leaf miners in their larval stage. The insects like flies can lay eggs on leaves and once they hatch, the larvae directly get into the leaf tissue to feed. This feeding action also protects them from predators that do not have the patience to look inside the leaves for food.

Leaf miners are also classified based on the type of damage they cause. For example, serpentine leaf mines are one of those. They make snake like patterns in the leaf and that is how they eat the tissue. Some are also called blotch leaf mines, whiles others are tentiform leaf miners. These mines are of different shapes and are classified based on it.

Different insects follow different way of eating the leaf. However, the cavities that they create within the leaf tend to rot the leaf and cause it to die. The leaf is the main source of nutrition and sunlight for the plant and when too many leaves die, the plant does not grow.

So, when it comes to finding out when are leaf miners active, it all depends on the life cycle of the adult insect. The insect will reproduce by way of eggs. These eggs are laid on the leaf or small holes made in the leaf. Once the eggs hatch, the larvae are released and that is when the leaf miners, or the insect larvae, become active.
