Food Plant: Malus domestica (Apple)

Egg: laid at the receptacle base

Mine: April-June

Notes: The first instar larvae mine the developing apples superficially, leaving a scar on the growing fruilet surface (as shown on Norfolk Royal Russet apple). Later instar larvae move to a nearby fruilet and burrow into it to reach the seeds, on which they feed. Some larvae may repeat this up to three times.The fully grown larva exits the fruit to form a cocoon in the soil.
