How do you take care of a moth that is sick?

you first of all put it somewhere where it wont fly away maybe a jar but dont forget to poke holes in it for air. put some flowers and grass in the jar. if the wing is broken that is not possible to fix. moths eat pollen and nectar from flowers so keep that in mind. or you can take it to your local zoo and they cand find out what species it is and tell you how to take care of it properly. i hope that helped
