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 main difference between a grasshopper and a cricket is that crickets tend to have long antennae, grasshoppers have short antennae. Crickets stridulate (sing) by rubbing their wings together, while grasshoppers stridulate by rubbing their long hind legs against their wings. Grasshoppers detect sound by means of little 'ears' at the base of their abdomen; in crickets these are on the front legs.
