He is about to end up run over, his mother saves himThey have huge swarms of grasshoppers invaded las vegas the past few days, to the amazement of residents and tourists.
It looks like a horror movie, but according to entomologists it is a common species in the desert, which it does not represent a danger to humans.
The phenomenon occurred due to a grasshopper migration moving north. So many swarms they gather when the winters and springs are particularly humid and rainy: in such climatic conditions, the grasshoppers accumulate in certain areas and then leave all together in a mass migration that gives rise to a real invasion.

The event is quite rare - in fact it occurs about once every ten years or so - and is not worrying e insects are not a problem for humans since they do not attack, do not bite, do not carry diseases and do not cause particular damage to gardens and crops.
Grasshoppers can only be a problem when driving, as huge swarms limit visibility.
In their migration, the insects would simply be attracted to the bright lights of the city, especially from the white lights. To remove them, it would be sufficient to install amber lights, which are not very attractive to grasshoppers.
The phenomenon would therefore not be worrying but it is still incredible and the grasshoppers are so numerous as to be even visible from weather radar.
? Some of you have been asking about the widespread radar returns the past few nights in #Vegas. Radar analysis suggests most of these echoes are biological targets. This typically includes birds, bats, and bugs, and most likely in our case–> Grasshoppers. ? #VegasWeather pic.twitter.com/reQX7hJR7Y
