It depends entirely on the bug and moreso the seasoning. I've eaten my share of ants and crickets in Mexico and South East Asia and the taste can vary wildly. I recall tasting the seasoning more than any buggy flavor.
On a side note, raw goat blood soup tastes exactly like you think it would... never again.
I ate some chocolate-coated crickets once. I'm not sure what they tasted like, but not chocolate. I also tried cornchips made with cricket flour instead of cornmeal. They didn't taste much of anything.
I had some deep fried crickets once. Just tasted like generic salty snack. Came in little packets my coworking place used to get as samples from various snack companies.
Achully the bug-taste in these people isn’t that strong. Some cumin and parsley will make them taste just like any other human. Veggies in the other hand are yum, and don’t need no extra seasoning
