Bee's collection (6)
I believe the answer is:
nectar
'bee's collection' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for nectar that I've seen before include "Heavenly drink, may create trance" , "Sugary plant fluid" , "That's sweet" , "Sweet fluid produced by flowers" , "Fluid secreted by flowers" .)
