Helicoverpa armigera is a species of moth in the family Noctuidae. It is known as the cotton bollworm, corn earworm, Old World (African) bollworm, or scarce bordered straw (the lattermost in the UK, where it is a migrant). The larvae feed on a wide range of plants, including many important cultivated crops. It is a major pest in cotton and one of the most polyphagous and cosmopolitan pest species. It should not be confused with the similarly named larva of the related species Helicoverpa zea.
This species comprises two sub-species: Helicoverpa armigera armigera is native and widespread in central and southern Europe, temperate Asia and Africa; Helicoverpa armigera conferta is native to Australia, and Oceania. The former sub-species has also recently been confirmed to have successfully invaded Brazil and has since spread across much of South America and reached the Caribbean. It is a migrant species, able to reach Scandinavia and other northern territories.
The cotton bollworm is very variable in both size and colour. The body length varies between 12 and 20 millimetres (1⁄2 and 3⁄4 in) with a wingspan of 30–40 millimetres (1+1⁄4–1+1⁄2 in). The fore... Wikipedia →

With luck
About 10% of wildlife watchers report a Cotton Bollworm Moth sighting in Table Mountain National Park on a given day, based on 82 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 66th most-seen of the 344 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.

GBIF citizen-science records
It is estimated from how often the Cotton Bollworm Moth is recorded against all the insects logged in Table Mountain National Park (82 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.
