OKLAHOMA — The National Weather Service (NWS) registered a mass migration of Monarch butterflies and dragonflies on its radar on Thursday!
According to a Facebook post by the NWS, the radar image shows a green, yellow, and red wave making its way across Oklahoma.
The massive group of butterflies and dragonflies were actually being carried by a north wind on a cold front that passed through the state on Oct. 5, said the NWS.
The yellow and red colors show the highest concentration of butterflies and dragonflies on the "leading edge" front of the group, while the green indicates the less populous mass following behind in a trail.
The NWS says their meteorologists typically use the radar "to track fronts and outflow boundaries, which are often the trigger for thunderstorm formation." The WSR-88D Weather Surveillance (Doppler) Radar caught the large migration of butterflies and dragonflies. To learn more, read below or click here.
