Leaf miner fly (Liriomyza spp.) Leaf miners are small flies whose larvae make tunnels in the leaf. The larvae drop before pupation and disappear underground.
By boring tunnels into leaves, stems, seeds or roots of plants, they cause a lot of damage.

Where to find

  • Vegetable garden and agricultural crops


Remove infested leaves; spray with pyrethrum if the infestation is large. Biological control with nematodes dramatically reduces the number of leaf miner flies.


Insect-proof mesh prevents the leaf miner fly from laying eggs. Parasitic wasps are the natural enemies of leaf miner flies.
