A swarm of bugs in northern Texas and southwest Oklahoma was so intense Wednesday that it appeared as a rainstorm on weather radar in the region.

Rangers at Copper Breaks State Park in Quanah, Texas confirmed the bug storm was made up of grasshoppers and beetles to the National Weather Service.

The swarm filled the air up to 2,500 feet and covered 50 miles.

Forrest Mitchell, Observations Program Leader at the National Weather Service of Norman, Oklahoma, told Popular Science that the fact they can pick up major insect swarms is a nod to the sensitivity of current weather forecasting equipment.

“It doesn’t take a whole lot of bugs to cause that on radar,” Kurtz said. “It’s not like biblical proportions. There was just enough out there that the radar picked it up.”

The Texas swarm was not the only major swarming of insects in the last week.

In Sabula, Iowa highway crews had to use winter snow plowing equipment to remove a swarm of mayflies from a bridge connecting Iowa and Illinois.

The crews not only used the plows to clear the bridge but laid down sand in an attempt to combat the slick conditions caused by cars crushing the bug swarm.

Officials say they will keep the lights on the bridge off during the next few weeks in an attempt to keep the bugs from swarming.
