I'm not sure I could eat bugs if I were starving. Last time I went on a ten day fast I got ravenous and I wanted to cheat, and the only thing in the house to eat was a package of dried seaweed "salad". I've always hated seaweed, but I find when I am hungry enough, such as after a fast, foods I used to dislike taste really really good. Not so for the seaweed. I smelt it, and took a nibble, and could not make myself eat it. Didn't matter how hungry I was.
With bugs, there is the emotional aspect wrapped up in it as well. I have no doubt I would end up vomiting if I did manage to down some bugs, but my gorges rises and my stomach gets upset at the very thought. The thing is though, if you are in a place full of insects, there are plenty of other things you can eat, like tree leaves, the inner layer of tree bark, roots, or even fungi, if you know what to look for. I have no doubt that there are plenty of bugs that would make you as sick as eating a bad fungus. I'd rather learn to recognize all the wild edible plants in my area, and in the area of anyplace I plan to visit, should a disaster strike and I end up lost in the wilderness. I'd even eat seaweed if I were stranded on that famous desert island people always ask us about, before I would eat invertebrates.
