Along with the apple maggot, it is the worm that people encounter when biting into an infested apple.
Because the larvae are not able to feed on leaves, they are highly dependent on fruits as a food source and thus have a significant impact on crops. The caterpillars bore into fruit and stop it from growing, which leads to premature ripening. Various means of control, including chemical, biological, and preventive, have been implemented. This moth has a widespread distribution, being found on six continents. Adaptive behavior such as diapause and multiple generations per breeding season have allowed this moth to persist even during years of bad climatic conditions.
Although the geographic origin of codling moths is unclear, there are theories of these moths originating from either Europe or the Mediterranean. Scholars believe that the codling moths were introduced to the Americas in the mid... Wikipedia →

With luck
About 10% of wildlife watchers report a Codling Moth sighting in Cévennes National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 437th most-seen of the 996 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May to July
In those months about 10% of wildlife watchers report a Codling Moth in Cévennes National Park on a given day, against under 5% in August to April, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Codling Moth sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Yes
Of the 4 parks where we can rate Codling Moth sightings, Cévennes National Park has the highest daily chance: about 10%. Next come Wadden Sea National Park (Germany, about 10%) and Bavarian Forest National Park (Germany, under 5%).
GBIF citizen-science records
It is estimated from how often the Codling Moth is recorded against all the insects logged in Cévennes National Park (17 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
