"We can probably blame the Book of Exodus," Jeff Lockwood, a professor of natural sciences at the University of Wyoming told The New York Times. "There are some special weather conditions that trigger the migration."ĭespite the size of the swarm, experts say that there is nothing to fear as the insects are not dangerous. "We have records clear from the 1060s of it happening, and I have seen it at least four or five times in my 30-plus years," he said. 🦗 #VegasWeather /reQX7hJR7Y- NWS Las Vegas July 27, 2019 This typically includes birds, bats, and bugs, and most likely in our case-> Grasshoppers. Radar analysis suggests most of these echoes are biological targets. 🤓 Some of you have been asking about the widespread radar returns the past few nights in #Vegas. "We'll have flights about this time of the year, migrations, and they'll move northward." "It appears through history that when we have a wet winter or spring, these things build up often down below Laughlin and even into Arizona," Jeff Knight, state entomologist from the Nevada Department of Agriculture, told Q13 Fox News. So far in 2019, Las Vegas has received nearly twice as much rain as it normally gets-a trend that also applies to the rest of Nevada-and has already exceeded its annual average rainfall (around 4 inches.) Experts say that the insects likely migrated to the area due to abnormally wet conditions. The swarms that have descended over the city over the past week are not unprecedented-they tend to occur every few years. This typically includes birds, bats, and bugs, and most likely in our case. "Radar analysis suggests most of these echoes are biological targets. "Some of you have been asking about the widespread radar returns the past few nights in Las Vegas," the National Weather Service tweeted. But closer inspection revealed that one of these areas represented something biological in origin, Reuters reported. On Saturday, meteorologists noticed that there were two areas of what looked like torrential rain on the radar map for Las Vegas. Ladybug swarm: Weather Service says a massive ladybug swarm was spotted.Las Vegas has been invaded by swarms of grasshoppers-and there are so many of the insects that they showed up on weather radar. In 2010, state agriculture officials geared up for a springtime invasion of crop-eating grasshoppers in northern Nevada. In three decades as an entomologist, Knight has seen the insects visit southern Nevada four or five times.
The state has records as far back as the early 1960s of Nevada grasshopper invasions. The jumpy bugs are likely to remain in transit across southern Nevada over the next several weeks, Knight said. That's why the insects are often found swarming glowing bulbs of white light.įlying ant day: Flying ants swarm into Britain in colossal hordes seen from space The grasshoppers are attracted to ultraviolet light. "They probably won’t cause much damage in a yard.” "They don’t carry any diseases, they don’t bite, they’re not even one of the species that we consider a problem," said Jeff Knight, an entomologist with the Nevada Department of Agriculture. Grasshoppers on the moveĪ wet spring expedited the insect swarm's northern migration, but the bugs are not dangerous. The most common "biological targets" captured on weather radar in southern Nevada are birds and bats. The National Weather Service upgraded its radar system in the spring of 2012.Įnhancements made the service's weather sampling capabilities much more sensitive, able to differentiate between large raindrops, small raindrops – and sometimes even biological entities. Grasshopper invasion: Grasshoppers are invading Las Vegas. “Haven’t seen something like this in a long time,” Guillet said. While some of the activity in the northern sector of the radar display included rain, a majority of the green coloring in the southern half of Las Vegas represented an insect invasion so large it registered on weather radar. The service posted a photo of the radar images to Twitter Friday night, showing what looked like a large storm moving east-to-west across the Las Vegas Valley. Most of the flurry found on the screen, she said, was a sprawling swarm of pallid-winged grasshoppers now plaguing the neon lights, streets and sidewalks of Las Vegas. " Insect swarms," National Weather Service meteorologist Kate Guillet said. LAS VEGAS – On Friday night, meteorologists in southern Nevada looked at the pulsing green images on the weather radar and discovered there was much more to it than the raindrops of scattered thunderstorms swirling on the screen.
