At least several types of locusts as I recall. It's been widely speculated that the dietary restrictions were really about parasites and other food safety concerns, but what's also famous is that they were quite legalistic about it. So if it was only permissible as desperation food, they would have said so... at length. Either way, Jews and other middle eastern groups with picky dietary rules, do have a long tradition for eating it in non-desperate times too. It's icky for us not used to it, but there's no reason to think parasites is a bigger issue with insects than with animals far more similar to us, which we do eat. Remember this article is about pet food insects, often fed to pets raw (if not alive), and it notes some extremely unsanitary practices in pet shops that farm them, such as feeding them on the excrement of the type of creature they're fed to. It's not particularly relevant for insects considered for human consumption.
