Technology can be a pretty amazing thing. Such is the case with Doppler radar. Doppler is used to monitor cloud cover and rain potential. It is so sensitive that it can tell how heavy or light the rain will be, if there is lightening or hail in the storm, or if there is a rotation indicating a tornado. Radar can detect wildfire smoke, bird migrations, and even bats. Amazing! But, did you know that it can also detect bugs. That’s right, bugs!

On Wednesday July 22, a strange sight appeared on the Doppler over a region of Texas. It was a huge span of what seemed like rain clouds, but there were no clouds. One call to the rangers at Copper Breaks State Park confirmed that what the radar was picking up was actually a swarm of grasshoppers and beetles. These flying pests were flying between the ground and 2500 ft. in an area as large as 50 miles. The swarms were not large enough to be considered of Biblical proportions, and actually couldn’t be seen by ‘the naked eye’ because the insects were all flying at different elevations – but the Doppler radar is so sensitive that it could pick up this strange phenomenon.
