It would be nice if we could have a debug option to see their exact names and then a config option where we can replace their names.

Maybe I could in the config add entity.BiomesOPlenty.butterfly.name = Butterfly

Not sure if wildcards and such could be possible too.

Thanks :)

Can you confirm this is still an issue in newer versions and open a new issue then?
