Flying fox (5,3)
I believe the answer is:
fruit bat
'flying fox' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for fruit bat that I've seen before include "Flying fox; bait turf (anag.)" , "Flying fox, for example" , "Large flying mammal" , "Long-snouted, large-eyed nectar feeder" .)
