After years of anticipation, it’s finally here…

For years we’ve dreamed of a tiny radio transmitter that was light enough to put on a monarch to follow it to the overwintering sites. The largest obstacle was always weight! Monarchs in our region weigh at most around 0.50 grams. Any transmitter was just too heavy, but continuing progress has enabled Cellular Tracking Technologies to create a tiny solar powered Bluetooth transmitter for monarch butterflies. 

The Cape May Point Science Center created an app so your smart phone can now track these radio-tagged monarchs up to about 1/4-mile away.
