Place and time for insect (6)
I believe the answer is:
locust
'for insect' is the definition.
(locust is a kind of insect)
'place and time' is the wordplay.
'place' becomes 'locus' ('place' in Latin).
'and' says to put letters next to each other.
'time' becomes 't' (abbreviation).
'locus'+'t'='LOCUST'
(Other definitions for locust that I've seen before include "beast resulting in destruction" , "Grasshopper of warm regions" , "Vegetation-destroying grasshopper" , "Sturdy, resilient" , "Part of destructive plague" .)
