A colorful, shimmering spectacle detected by weather radar over the U.S. state of Colorado has been identified as swarms of migrating butterflies. Scientists at the National Weather Service (NWS) first mistook the orange radar blob for birds and had asked the public to help identifying the species. They later established that the 70-mile wide (110km) mass was a kaleidoscope of Painted Lady butterflies. Forecasters say it is uncommon for flying insects to be detected by radar.
