Synthesiomyia nudiseta
In 3 days ~30% in a week ~60%
Synthesiomyia nudiseta is one of the largest flies in the family Muscidae. The fly has a pair of forewings; the paired hind wings have been reduced to halteres that help with stability and movement during flight. Key characteristics of this species include plumose (that is, "feathery") segmented aristae, well-developed calypters, and sternopleural bristles. Synthesiomyia nudiseta is a forensically important species because it is necrophagous and can therefore help determine the time of colonization for the post mortem interval with its known life cycle.
The species Synthesiomyia nudiseta, was named by Frederik Maurits van der Wulp in 1883; and S. nudiseta is the only known species under the genus Synthesiomyia. Synthesiomyia nudiseta is essentially a kind of necrophagous fly. Larvae of S. nudiseta were found in a cadaver in Costa Rica, and the larvae have also been shown to be important on decomposition of carcasses in Malaysia. S. nudiseta are said to be useful in the recognition of the range of post-death, and of importance to forensic entomology. In Brazil, S. nudiseta is very common in Rio de Janeiro, where it is highly synanthropic. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Synthesiomyia nudiseta is recorded against all the insects logged in Zhuhai [Macau] (15 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.
