Codling moth caterpillar larvae damage fruit such as apples, pears, stone fruit and walnuts.
Codling moth adults are grey with light grey and pale brown stripes on their wings. Females lay eggs on fruit or leaves and the black-headed yellow caterpillars eat into the fruit soon after hatching. Each larva burrows into the fruit, feeds on the fruit pulp and seeds for approximately three weeks before exiting to overwinter and pupate elsewhere.
Visible damage occurs to fruit when the young codling moth caterpillars burrow through the skin. In apples they can consume the seeds and much of the core. Codling moth are prone to attack apples, pears, stone fruit and walnuts.
Warmer areas of New Zealand usually have two generations of codling moth each year, and cooler areas just one. They usually appear October through to February.
