Leafminer is a maggot in the larval stage of an insect family commonly found in home gardens, feeding on the middle surface of the leaves. There are different kinds of leafminers; however, their appearance and damage are the same. Leafminers are undistinguished black flies that do not cause harm to the leaves; instead, it’s the larvae. The favorite plants of this larva are beans, cabbage, spinach, beets, lettuce, and various fancy flowers like lilacs, broadleaf trees, and other shrubs.

Get A QuoteAdult leafminers are 1/10 inch in length, black flies with stripes of yellow and transparent wings. Their look is completely identical to that of small, hunched black house flies that lay a group of eggs under a leaf. Their larvae are 1/3 inch long and are often light green or yellow in color. Once the eggs hatch, the larvae burrow into the leaf tissue and begin feeding from within, creating visible winding trails or blotches. Over time, this internal feeding weakens the plant and affects its overall health and growth.
A mature larva drops itself into the soil of its host plant to pupate. After 2-4 weeks, it will become a fly. A female leafminer can lay up to 250 eggs under the leaf using its ovipositor. These eggs appear as an elevated spot on the surface of the leaf and will hatch within 10 days. They will pass through the mid-leaf tissue, feeding and leaving squiggles visible on the leaf’s surface. When they mature after 2-3 weeks and are ready to pupate, they will cut a hole in the leaf and drop to the soil. There are several generations each year.
Leafminers, as their name implies, are good at mining through the leaves, feeding while leaving yellowish wavy lines on the leaves of the crop. Their damages may also appear as spots. They can attack various plants, from crops to trees, shrubs, and flowers. Damage depends on how severe the infestation is, but initially, the damage can be small. However, as the leafminers increase in number, though it may not kill the plant, it can make it look unpleasant by crippling its leaves to hardiness. Leafminers cause the crops to lose their value and even restricts its growth, leading to a poor harvest in home gardens. They are very fond of attacking spinach, and if such a crop is heavily infested, there is no way to save the affected leaves.
If an issue exists, there are ways to solve it as well. Early detection of leafminer infestation and taking precautionary measures keep the severity of the issue under control. There are many ways to control the leafminer problem. Scouting is an important part of detecting these culprits as early as possible. Examine the underside of the leaves; look for small clusters or white eggs, and examine the seedlings weekly. Early detection means early prevention.
