In my own writing, I use morality to refer to what people ought and ought not do based on cultural moral norms and our moral sense’s judgments. There are often strong feelings of right and wrong about morality. Violators of morality are commonly thought (in a culture) to deserve punishment.
Ethics includes morality as described but also includes philosophical claims such as utilitarianism, Kantianism, and virtue ethics that have little emotional content or relationship with cultural moral norms and our moral sense’s judgements. Ethics also includes topics such as journalistic ethics or business ethics that may also seem to have little to do with cultural moral norms and our moral sense. Ethical violators (outside of morality) may not be thought to deserve punishment. For example, if you lie to the murderer where his next victim is (as required by Kantianism) or if you do not sacrifice your life for a small benefit for billions of people (as utilitarianism might require) will you commonly be thought to deserve punishment? No.
It seems useful to me to think of them as separate concepts.
However, I see ethics and morality commonly used interchangeably. So not everyone agrees they are different.
