Features
- Named 'leaf miner' because larvae mine or tunnel between the upper and lower surfaces of leaves, feeding on internal leaf tissue
- Adults are small black and yellow flies measuring 1.5-3 mm long. Larvae are tiny yellowish maggots that are nearly transparent. Create characteristic serpentine trails in leaves
- Larvae tunnel through leaf tissue between upper and lower epidermis, consuming cells as they move. Adults puncture leaves to feed and lay eggs
- Create winding, serpentine white or tan trails visible on leaf surfaces. Trails widen as larvae grow. Heavy infestations cause leaves to yellow, drop prematurely, and reduce plant vigor
- Adults lay eggs inside leaf tissue. Larvae hatch and mine for 4-6 days through 3-4 instars. Pupate in soil or on leaves. Complete lifecycle in 21-28 days. Multiple overlapping generations per year
- Adult flies measure 1.5-3 mm long. Larvae grow to 2-3 mm long. Eggs are microscopic, about 0.2 mm
- Thrive in warm weather with temperatures around 25°C (77°F). Most active in spring and summer. Can produce 10 generations per year in warm climates
- Attack spinach, lettuce, Swiss chard, beets, celery, tomatoes, peppers, beans, cucumbers, melons, citrus, chrysanthemums, and many ornamental plants
- Prevent by using row covers, removing infested leaves promptly, rotating crops, tilling soil after harvest, keeping garden weed-free, and using yellow sticky traps to monitor adults
- Natural predators include parasitic wasps (Diglyphus, Chrysocharis), lacewings, and beneficial nematodes. Remove and destroy mined leaves. Treat with neem oil or spinosad. Squeeze leaves to crush larvae inside tunnels
