Zelus longipes
In 3 days ~30% in a week ~60%
Zelus longipes is an assassin bug (Reduviidae) that is a member of the Harpactorinae subfamily. Its distribution ranges include southern North America, Central America, and South America (except Chile), especially in agroecosystems in Brazil.
Zelus longipes has been considered as a potential biocontrol agent, as it prefers caterpillars of Spodoptera frugiperda, which is a moth that is a pest in cornfields. The species is a generalist predator, commonly used to combat picture-winged flies (Diptera: Ulidiidae), which cause damage to sweet corn yields in Florida. Z. longipes prefers smaller caterpillars, probably because there is less risk of injury while subduing smaller prey. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Milkweed Assassin Bug is recorded against all the insects logged in Volcán Barú National Park (6 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.
