Exact place and time for destructive insect (6)
I believe the answer is:
locust
'destructive insect' is the definition.
(I've seen this before)
'exact place and time' is the wordplay.
'exact place' becomes 'locus' (I've seen this before).
'and' says to put letters next to each other.
'time' becomes 't' (abbreviation).
'locus'+'t'='LOCUST'
'for' acts as a link.
(Other definitions for locust that I've seen before include "Destroyer" , "Swarming, devouring, insect" , "Destructive creature" , "plaguey type" , "Sturdy, resilient" .)
