The European corn borer (Ostrinia nubilalis), also known as the European corn worm or European high-flyer, is a moth of the family Crambidae. It is a pest of grain, particularly maize (Zea mays). The insect is native to Europe, originally infesting varieties of millet, including broom corn. The European corn borer was first reported in North America in 1917 in Massachusetts, but was probably introduced from Europe several years earlier. Since its initial discovery in the Americas, the insect has spread into Canada and westwards across the United States to the Rocky Mountains.
The adult European corn borer is about 25 millimetres (0.98 in) long with a 26–30 millimetres (1.0–1.2 in) wingspan. The female is light yellowish brown with dark, irregular, wavy bands across the wings. The male is slightly smaller and darker.
European corn borer caterpillars damage corn by chewing tunnels through many parts of the plant, leading to a decrease in agricultural yield. The European corn borer is native to Europe and was introduced to North America in the early 20th century. This moth plagues corn crops in France, Spain, Italy, and Poland. In North America, the European corn... Wikipedia →

Rare
Under 5% of wildlife watchers report a European Corn Borer Moth sighting in Paris on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 519th most-seen of the 916 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
August
In that month about 10% of wildlife watchers report a European Corn Borer Moth in Paris on a given day, against under 5% in September to July, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most European Corn Borer Moth sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
7th of 7
Of the 7 cities where we can rate European Corn Borer Moth sightings, Paris ranks 7th at under 5%. The best odds are in Turin (Italy, about 10%), Milan (Italy, about 10%) and Berlin (Germany, under 5%).
Same family: Crambidae
The closest relatives of the European Corn Borer Moth that you can see in Paris (family Crambidae, Crambid Snout Moths) are Box Tree Moth (about 10%), Straw-Barred Pearl (about 10%) and Narrow-Winged Grey (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the European Corn Borer Moth is recorded against all the insects logged in Paris (17 verified sightings), 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.
