### Identification The African Fig Fly (*Zaprionus indianus*) is a dapper little drosophilid that is remarkably easy to spot if you know what to look for. Measuring approximately 3mm, its most striking field mark is a pair of brilliant, silvery-white "racing stripes" that run longitudinally from the head, across its large reddish eyes, and down the entire length of the golden-yellow thorax. Each white stripe is framed by thin, sharp black borders, making them pop against the fly’s warm amber body. Unlike the common vinegar fly, its body is more robust and its coloration more vibrant, looking almost like a miniature piece of jewelry perched on a ripening fruit.
### Habitat & Range Originally native to tropical Africa, this fly has become a world-class hitchhiker. It invaded South America in the late 1990s and has since marched steadily northward through the Caribbean into the Southern United States. You will find it in humid, warm ecosystems—specifically orchards, suburban gardens, and tropical hardwood hammocks. It thrives from sea level up to mid-elevations, provided there is a steady supply of fermenting fruit.
### Behaviour Observed in the field, *Z. indianus* is a bold opportunist. While many fruit flies wait for fruit to fall and rot, this species is often seen on fruit still hanging on the branch. It is a diurnal flyer, most active during the warm hours of the morning and late afternoon. You’ll likely notice them congregating in small groups on the skin of a ripening fig, where males perform subtle wing-flicking displays to court females.
### Diet This species is a generalist with a sweet tooth. While it is famous for its love of figs—where it feeds on the yeast and sugars of the fruit—it has been recorded on over 70 different host plants, including citrus, guava, and berries. It doesn't "hunt" in the traditional sense but uses its keen chemoreceptors to track the scent of ethanol and acetic acid.
### Fascinating Fact The African Fig Fly is a "thermal specialist." While most fruit flies retreat to the shade when temperatures soar, *Z. indianus* can remain active and productive in extreme heat that would be lethal to its competitors, allowing it to colonize sun-drenched habitats where other flies simply cannot survive.
