> 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? | |||||||||||||||||

This subject was on here a while back, but this is the first article with truly engaging photos of the transmitter and the process of application up-close. This is super cool! I was/am surprised no one has talked about the espionage implications of something like this. You really can put a track on anything. | |||||||||||||||||

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