Adult codling moths are small, about 10 mm long with a 20 mm wingspan, and have distinctive brown spots surrounded by gold rings on their fore-wings. Their larvae feed inside fruits, stopping growth and leading to early ripening, which makes them a serious pest for orchards.

How to recognize it

The fore-wings show brown spots edged with golden rings, called “little mirrors.” The antennae are slender and curve slightly near the tip.

Is it a pest in the house?

The caterpillars bore into fruit, stopping growth and causing early ripening, making the moth a major pest for fruit growers.

Source: Wikipedia

How to get rid of it

Control methods include chemical, biological, and preventive approaches; a caterpillar needs about 45 minutes to bore into fruit and 15 minutes to seal the entry.

Where it lives

Moth viability depends on humidity and climate, and all life stages are found on host plants where the larvae feed.

What it eats

Larvae cannot eat leaves; they rely on fruit, boring into it and causing premature ripening.

Life cycle

Second-generation adults emerge in spring, from late April to early June in the Northern Hemisphere, with timing linked to temperature.

How this page works

This is one bug's fact sheet. The colored box at the top says whether it is dangerous. Sections below cover how to recognize it, whether it is a pest, and how to deal with it. The US map shows which states have records; tap a state to see other bugs there.

Every fact on Bug FAQ comes from a named source (university extension sites, government agencies, GBIF, iNaturalist, Wikipedia). The source is linked next to each section. If we have no source for something, we leave it out.
