Grasshopper of warm regions (6)
I believe the answer is:
locust
'grasshopper of warm regions' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for locust that I've seen before include "Destructive winged insect" , "Destructive creature" , "Voracious African or Asian grasshopper" , "Sturdy, resilient" , "Vegetation-destroying grasshopper" .)
