Ostrinia furnacalis is a species of moth in the family Crambidae, the grass moths. It was described by Achille Guenée in 1854 and is known by the common name Asian corn borer since this species is found in Asia and feeds mainly on corn crop. The moth is found from China to Australia, including in Java, Sulawesi, the Philippines, Borneo, New Guinea, the Solomon Islands, and Micronesia. The Asian corn borer is part of the species complex, Ostrinia, in which members are difficult to distinguish based on appearance. Other Ostrinia such as O. orientalis, O. scapulalis, O. zealis, and O. zaguliaevi can occur with O. furnacalis, and the taxa can be hard to tell apart.
This moth exhibits unique acoustic mimicry of a predator by mirroring the echolocation calls of bats in order to temporarily paralyze female moths and make it easier to mate. It is also well known as being an agricultural pest on several crops in the western Pacific region of Asia, especially on corn. The Asian corn borer is second only to maize downy mildew as the most prevalent corn pest. There is currently extensive research on eradicating this pest from corn crop in Asia, including the use of biological agents and toxins... Wikipedia →

Rare
Under 5% of wildlife watchers report an Asian Corn Borer sighting in Kaohsiung on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 201st most-seen of the 218 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February, June and December
In those months about 10% of wildlife watchers report an Asian Corn Borer in Kaohsiung on a given day, against under 5% in January, March–May and July–November, the lowest months.
Only Kaohsiung, in our data
Kaohsiung is the only city on Wallace's Line with enough records to rate Asian Corn Borer sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Asian Corn Borer is recorded against all the insects logged in Kaohsiung (5 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.
