Can weather radar be used to track swarms other than mayflies? Along the Mississippi River swarms of emerging mayflies have been seen on radar.  The radar and image below are from a July 11, 2017 emergence near LaCrosse, Wisconsin.  On the radar you can see the mayflies emerge from the river and head toward the north.



This image was taken in LaCrosse during the emergence.

Is it possible that other swarms have or can be tracked by weather radar?
Bird migration has been studied by Weather radar Bird migration study using weather radars  and the monitoring can be visualized here - Bird migration density profiles. A github site Time Integrated Multi altitude Migration Patterns  has been developing algorithms to estimate the density, speed and direction of migration movement at different altitudes around a radar.
