Son of Daedalus (6)
I believe the answer is:
'son of daedalus' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for icarus that I've seen before include "In Greek myth, he flew too close to the sun and died" , "Mythical flier who went too near the sun" , "Foolhardy flier" , "Ancient Greek who flew so high his wings melted" , "His false wings melted" .)
