    Can a ‘magical’ insect help Madagascar battle malnutrition, deforestation?

    The black soldier fly is considered delicious and nutritious. Researchers hope the flies can help reduce malnutrition and pressure on forests, as well as improve access to affordable organic fertilizers.

    By Sara Jerving // 28 November 2025

    On the roof of the Madagascar Biodiversity Center in the capital city of Antananarivo is a hut, nicknamed the “Love Shack.” Inside are mating black soldier flies.

    The larvae of these bugs are rich in protein and lipids, prompting researchers and the development sector in the country to see them as a potential solution to reduce malnutrition, ease pressure on forests, and improve access to affordable organic fertilizers.

    It’s a tall order for such a small creature. But these soldiers have a lot of good qualities. And while they aren’t a replacement for all livestock, they are much easier to farm on a small scale, and they convert low-value organic residues into biomass that can be used as fertilizer or high-quality protein for feeding farm animals.
