I believe there are 2 methods, either examining the palps or the hindwings.

Is it possible to examine the hindwings of a live moth without damaging it?

Probably not

Unless it naturally opens its wings, although maybe if you have it in a specimen pot a view of the underside against the light. That might just show enough detail, not sure though never tried it.

Depends what you mean by damage

it will lose some scales in the process but you can examine them live if you get a good grip, or can knock them out with ethyl acetate and examine them unconscious.

Pretty sure

the palps method has been shown not to work. So underside of hindwing or examination of genitalia are the options.
