I assumed the bees were using the honeydew as a nectar source, and converting it into honey. Is that not true?
Bob I was totally under the 'very same' assumption and understanding as you about honeydew (honey). I also think it is safe to assume bees must have the very same assumption as well! lol
However, Mr Binnie and Mr Bush both broke the subject down to the foundation. If I understand each of these folks correctly, Honeydew can not 'officially' be considered true Honey though called such when collected, converted, and stored by bees, just as done with 'true nectar' honey.
See 2:24 to 3:12 in Mr Binnnies video....
I suppose the same can be said of bee collected and converted 'sugar water' not being real honey, just as said of honeydew not being real honey for example, though two totally different sources neither being 'real honey' collected from real nectar, and rightfully so when we consider. Mr Binnies displayed written text in the video really helps explain Honeydew.
This has turned out to be an interesting topic!
