Hermetia illucens, known colloquially as the black soldier fly, is a widespread fly of the family Stratiomyidae. Black soldier fly larvae are commonly utilized in composting systems due to their ability to rapidly break down food waste.

This species is native to the Neotropical realm, but in recent decades has spread across all continents, becoming virtually cosmopolitan. It is present in parts of North America and Europe, including the Iberian Peninsula, southern France, Italy, Croatia, Malta, the Canary Islands, and Switzerland, and on the Black Sea coast of Russia in Krasnodar.

GBIF citizen-science records
It is estimated from how often the Black Soldier Fly is recorded against all the insects logged in Denpasar (19 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.
