An analysis has been carried for rainfall data in the Czech Republic over the period 1961 to 2011 (10). The contribution of heavy, short-term precipitation to the precipitation total significantly increased at about half of 17 weather stations spread over the country. However, whether these changes are due to climate change is yet unclear.
Best Answer: Locusts and grasshoppers are identical in appearance - how they differ is in their behaviour. Locusts can exist in two different behavioural states (solitary and gregarious) whereas grasshoppers generally do not. When the population density is low, locusts behave as individuals, much like grasshoppers.
The act of swarming, or exhibiting a so-called gregarious phase, is the most obvious characteristic that identifies a subspecies of grasshopper as a locust. And in fact, the tendency to swarm together is a relatively recent phenomenon in grasshopper evolution. However, what we have in New Mexico is an uncharacteristic swarming by members of the Acrididae family, which are the non-swarming members of the grasshopper designation.
