Once when I visited Mexico they had a plague of these glowing in. They're were so many, all over the place. It was disgusting. The roads were smeared with bug guts that have been roasting in the hot Mexico sun.
They're were so plentiful that the chickens at my grandma's refused to eat them. They got tired of eating so many.
I have some serious suspicion it's just evolution conditioning our brain to not try and eat these mofos. And maybe to stay away because some of them can give you a nasty bite (I mean, whatever that has way too many legs). Except people living under the most harsh conditions, having to resort to cricket thighs and locust butts.
It's more likely that in the developed world we've eliminated most of the critters that look like this so we're just not used to seeing them. People in Papua New Guinea aren't skeeved out by this kind of bug - they snatch them up and eat them when they see them.
I don't know, maybe. I'm also very disgusted by shrimp and other shellfish with their shell intact. But we do eat those, and people hunt them without fear. And people keep crickets as pets and touch insects without fear, think they look "cute" etc. Insanity to me but, it doesn't affect them like it does me.
