Las Vegans were hit with an explosion of grasshoppers. The question many of you have been asking is “what is the difference between a locusts and grasshoppers ?”
Well, they are in fact one in the same.
Locusts are not a species. Locusts are, in fact, brown grasshoppers that have developed gregarious behaviors as a result of overpopulation.
Drought drives locusts to crowd in small areas where there is vegetation. Locusts then abandon their solitary phase as grasshoppers and reproduce at dramatically high rates forming bands of nymphs and swarms as adults.
When grasshoppers begin reproducing at these rates, they become locusts. These are why people fear locusts, not grasshoppers. Locusts have been disastrous to crops.
