Entomophagy is a fancy Greek-derived word for a simple concept: eating bugs. It's not a particularly common habit in the West—at least not among people older than 2—but edible insects have been a component of diets across the world since prehistoric times. In fact, the United Nations' Food and Agriculture Organization has suggested insects, which are a good source of protein and vitamins, could be a solution to resource scarcity and pollution caused by farming.

Organized by the nonprofit Little Herds, Austin's Bug Festival has been spreading the word for years about the use of insects as eco-friendly and economically viable food for humans, pets, and livestock. At the kid-friendly event, visitors can learn about cultures where insect eating is typical, sample bug-based treats, and watch cooking demonstrations. They can also visit the booths of local vendors and organizations focused on sustainability.
