Entomophagy is the human consumption of insects and arachnids in the form of eggs, larvae, pupea (transformational life stage of some insects), and adult.
Many cultures have been eating insects for thousands of years, and although often seen as taboo in the Western world, it is common in many developing counties, with 80 percent of the world's nations eating over 1,000 different species.
The consumption of insects has several environmental benefits, in comparison to other meat based protein sources. Insects require less resources to produce (i.e. land and water), can be raised on organic side-streams, and emit fewer greenhouse gases and ammonia.
