Noisy summer insect (6)
I believe the answer is:
cicada
'noisy summer insect' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cicada that I've seen before include "Flier" , "Shrill bug" , "Chirpy insect" , "Droning insect" , "The insect produces a high-pitched sound" .)
