As a vegetarian, I personally don't see much difference between eating a mealworm and eating a cow. I'm sure bugs are delicious; shrimp and lobsters are basically bugs, right?

As a predatory omnivore... well, a carrion-eating omnivore actually, seeing that I don't hunt myself and instead buy parts of corpses that have been dead for days... I don't see much difference between eating a chicken leg and a head of lettuce

The only difference is that my meat is already dead, whereas the lettuce is still alive and breathing when I eat it. It seems crueler to me to bite into respiring, living tissue that might grow roots again if you put it in soil, but I don't care as long as it's healthy and tastes good.
Anyway, you're correct that there isn't much of a difference between insect larvae and shrimps. Both are arthropods, and both are quite healthy (low in fat, high in protein). I love shrimps and lobster and would give mealworms a try. What I wouldn't eat though is locusts, because they're served in the carapace. I prefer my meat without a chitinous wrapper. If it's too much effort to peel the bugs, they're not worth eating.
