A Parktown Prawn are widely mistaken as crickets, although they are more closely related to grasshoppers. This common misassumption is due to the fact that parktown prawns are generally darkish brown, rather than green. They are found in every continent on the planet, with the exception of Antarctica.
These critters are usually around 4 to 5 centimeters in length, with an antennae of 2 cm. More information can be found by using a search engine ([[1]],[[2]], etc) and searching this topic.
