theres no such thing!
You are wrong! There is a bumblebee moth that frequents my
garden And here is a website you can copy and paste to see pics of
them and information on them.

I also have a pic of one. Here it is. Thought it was a
hummingbird at first but, after further research found it to look
more like the Bumblebee moth.
It likes to feed on my hummingbird bush and flies like a
hummingbird very quick. Easy to mistake it for a hummingbird.
