 There is no evidence that newly hatched larvae would burrow down and locate tubers using the root system.On foliage, the larvae mainly feed on the mesophyll, leaving brown or white spots in the leaves, known as blotch mines.The potato tuber moth has been found to feed on various members of the family Solanaceae such as tobacco plants ("Nicotiana tabacum"), eggplants ("Solanum melongena"), tomatoes ("Lycopersicon esculentum"), and bell peppers ("Capsicum annuum").
