There’s something to the “if you’re hungry, you eat what’s available” theory. A while back, I read an article (check out the link, there’s a picture of a basket of spider ) on fried spiders in Cambodia being considered a delicacy. Evidently, the Cambodians started eating spiders (among other things) during the desperate days of the Khmer Rouge and devloped a taste for spider. (eeeww)
Since spiders are one of the only insect-type things the Cambodians still consume, I’m betting the other bugs weren’t tasty.
