I agree with your identification of Madagasca Bee moth but if you "Google" Galleria mellonella it comes up with Greater Wax moth???? Two insects can't have the same name. Any ideas? Have I spelt it incorrectly?
This is the Pleasant Hornet Moth Euchromia amoena (family Arctiidae, subfamily Ctenuchinae). It lives in Madagascar, but also in mainland Africa.
