I'm not wishing to do eat these but I have learned from the rural folks that they usually eat snails and beetle when money does not arrive. The snails are cooked in coconut milk and added are vegetables to enhance the flavor. With beetle, it is fried and eaten together with chili and some herbs, again, to enhance the taste. Snails thrive in wet places like river, stream, lake or even pond. Makeshift fish ponds have lots of snails. So gathering snails is not much of a problem if the area has some wet places. With beetle, they are normally in the trees. One of the best ways to gather beetle is to make a fire to create smoke that would make the beetle get down on the ground. That would be easy to gather then. However, in times of calamity, I don't think there would be the convenience of cooking especially if you do not have the utensils and other ingredients. With the snails, they have to be broiled in open fire and eaten just like that. How about beetle? It can be boiled using bamboo cylinder with a little water and salt.
