Edible insects may not be considered a delicacy in the West but for many cultures, they are an important source of protein. In Thailand, over 50 species of insects may be consumed throughout the year, and in Ecuador 83 different species have been recorded as an important complement to other sources of animal protein. In Japan, insects are sold as canned foods and in China, many insects are consumed for medicinal purposes. Overall, around 2000 edible insect species have been recorded around the world.
Traditional consumption involves eating the insects raw, boiled or roasted.
However, for those not used to adding insects to their daily menu, they can be powdered and used as flour. These beetles are small, reproduce quickly and are resistant to disease and parasites. The mealworms can be fed on oats or other types of grain and moisture is provided by pieces of vegetable or fruit. Larvae can be harvested from the first generation and used as required because insects, like meat, deteriorate quickly. They can be killed by freezing or boiling.
