Place and time for an insect (6)
I believe the answer is:
locust
'an insect' is the definition.
(locust is a kind of insect)
'place and time' is the wordplay.
'place' becomes 'locus' (I've seen this before).
'and' is a charade indicator (letters next to each other).
'time' becomes 't'.
'locus'+'t'='LOCUST'
'for' acts as a link.
(Other definitions for locust that I've seen before include "Swarming, destructive insect" , "It strips plants" , "Swarming, devouring, insect" , "A deadly grasshopper seen in plagues" , "Grasshopper of warm regions" .)
