I accidently broke a wing once. Half a forewing, but still attached by a little bit, though it was dangling. The monarch could not fly until I tore the dangling half off, then amazingly it could fly. Not that great, but able to get to flowers at least. I always wondered if it would be possible to carefully superglue/graft a wing back together. I don't like to mess with living things like that though. I'd put it in the freezer.
