Sacred Egyptian insect (6)
I believe the answer is:
scarab
'sacred egyptian insect' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for scarab that I've seen before include "Beetle revered by ancient Egyptians" , "Large dark beetle" , "Egyptian stone" , "divine creature" , "Beetle considered divine by ancient Egyptians" .)
