Interesting question. From :
While the human midbrain and the insect brain may even be evolutionarily related, an insect’s inner life is obviously more basic than our own. Accordingly, bugs feel something like hunger and pain, and “perhaps very simple analogs of anger,” but no grief or jealousy. “They plan, but don’t imagine,” Klein says. Even so, insects’ highly distilled sense of self is a potential gift to the far-out study of consciousness. Probing the insect brain could help quantify questions of what it means to think that vexed the likes of Aristotle and Descartes, and could even aid the development of sentient robots.
A lot depends on what one thinks consciousness even is. Jealousy would likely be meaningless to an insect because it depends on conditional, potentially changeable relationships. Middle Dog is jealous of Top Dog because he sees that he could be Top Dog himself and appreciates the advantages. But how likely is it that a worker ant is “jealous” of the ant queen?

Would we give up naturalism to solve the hard problem of consciousness?
