Soldier flies (Stratiomyidae) are a widespread family of true flies, with more than 2,700 species found around the world. They are often admired for their brilliant metallic colors and striking eyes. While the adults are harmless flower visitors that feed on nectar, their larvae play a very different — and equally important — role as decomposers of organic waste, making them valuable allies in both natural ecosystems and agriculture. The genus Sargus includes some especially charming metallic soldier flies. As adults, they can be seen visiting flowers during the day, while their larvae develop in decaying organic matter such as compost and cow dung, helping transform rotting material into nutrient-rich soil. I encountered this beautiful green individual in La Concordia, in Ecuador’s Santo Domingo Province, where it was quietly basking in the sun.
