"Considerable empirical evidence supports the assertion that insects feel pain and are conscious of their sensations. In so far as their pain matters to them, they have an interest in not being pained and their lives are worsened by pain. Furthermore, as conscious beings, insects have future (even if immediate) plans with regard to their own lives, and the death of insects frustrates these plans. In that sentience appears to be an ethically sound, scientifically viable basis for granting moral status and in consideration of previous arguments which establish a reasonable expectation of consciousness and pain in insects, I propose the following, minimum ethic: We ought to refrain from actions which may be reasonably expected to kill or cause nontrivial pain in insects when avoiding these actions has no, or only trivial, costs to our own welfare."
