Rocky Mountain locust (SciiFii)

The Rocky Mountain locust (Melanoplus spretus) is a species of grasshopper that ranges through the western half of the United States and some western portions of Canada with large numbers seen throughout the central portion of its range. This species was once extinct since the earliest 20th century, but has since been brought back from extinction by SciiFii and reintroduced throughout the species original range to help boost biodiversity. Many people were concerned about the de-extinct Rocky Mountain locusts eating the crops, however, the crops across the United States, Mexico, and Canada have all been genetically modified by SciiFii to be resistant against Rocky Mountain locusts, so the farmers and gardeners could be prepared for the Rocky Mountain locusts' return. The Rocky Mountain locusts are so social that their swarms in numbers far larger than any other locust species can be reported, with some swarms estimated at 198,000 square miles (510,000 km) in size (greater than the area of California), weighing 27.5 million tons and consisting of some 12.5 trillion insects, the greatest concentration of animals ever guessed, according to Guinness World Records. The conservation status of the Rocky Mountain locust is Least Concern due to successful conservation efforts and the Rocky Mountain locusts' wide natural range.
