> The transmitter lets out a signal every second on 2.4 gigahertz, which is in the frequency range of Bluetooth receivers. Any smartphone or tablet within 100 meters of a BlūMorpho will acknowledge the signal and pass it on to the Project Monarch server, whether it has the app downloaded on it or not, provided Location Services and Bluetooth are turned on.
Is this accurate? If so, I am really curious how this works. Are they effectively sticking Airtags on butterflies?

Download the app and appears to be working, the paths plotted on the map on the west coast make sense.

Truly impressive technology. I would have been very confident it was impossible to put an RF tracker on a butterfly.
