Washington - Las Vegas expected another night of swarming grasshoppers on Saturday after a Nevada state entomologist warned residents and visitors they will be around for a few weeks.
Photos and videos of grasshoppers flying under the lights of casinos along the city's Strip of hotels and entertainment venues began appearing on social media earlier this week.
People commenting about the insects on Twitter compared the situation to scenes from horror films and referred to biblical passages about signs of the apocalypse.
But Nevada state entomologist Jeff Knight said residents and visitors needn't worry. The bugs don't carry diseases or bite and "probably won't" cause any damage to foliage, Knight said in a blog post.
"They generally just eat weeds," Knight said. "When there are so many, they tend to move and are headed north," he added, saying they are likely to be around for a few weeks.
