Insects might be more economical, or at least eventually when their production is more mainstream. But food is relatively cheap today anyway; what is expensive is rent/or mortgage. Food for a single, working person doesn't really make such a dent in the budget that they are forced to thin "damn, there has to be some alternative to this", compared to what they spend on their rent. So I don't think it's that much incentive to eat insects, from an economical perspective.
