To replace fishmeal and soy in animal feed, farms increasingly raise one insect whose larvae devour food waste and are then dried into protein-rich meal.
The black soldier fly is the insect most widely farmed to replace fishmeal and soy in animal feed, because its larvae are remarkably efficient at consuming food waste and converting it into body mass rich in protein and fat. Once grown, the larvae are harvested and dried into a nutrient-dense meal fed to fish, poultry, and pets.
Monarch butterflies are prized for their beauty and long migrations, not for any role in industrial feed production, and their larvae feed exclusively on milkweed rather than food waste. Honeybees are farmed for pollination and honey production, an entirely different agricultural purpose unrelated to converting waste into animal feed.
Regulatory approval of insect protein for certain animal feeds in places like the European Union has helped fuel rapid growth in this industry, since black soldier fly farming can turn an environmental waste problem into a valuable feed product.
