What accompanies this insect in Susan Coolidge's book (7)
I believe the answer is:
katydid
'what accompanies this insect in susan coolidge's book' is the definition.
'katydid' can be an answer for 'insect' (katydid is a kind of insect). I am not certain of the rest of the definition.
This is all the clue.
(Other definitions for katydid that I've seen before include "American grasshopper" , "American bush cricket" , "Large cricket" , "US bush cricket" , "insect" .)
