An anonymous reader quotes a report from the New York Times:
> For the first time, scientists are tracking the migration of monarch butterflies across much of North America, [1]actively monitoring individual insects on journeys from as far away as Ontario all the way to their overwintering colonies in central Mexico. This long-sought achievement could provide crucial insights into the poorly understood life cycles of hundreds of species of butterflies, bees and other flying insects at a time when many are in steep decline.
>
> The breakthrough is the result of a tiny solar-powered radio tag that weighs just 60 milligrams and sells for $200. Researchers have tagged more than 400 monarchs this year and are now following their journeys on a cellphone app created by the New Jersey-based company that makes the tags, Cellular Tracking Technologies. Most monarchs weigh 500 to 600 milligrams, so each tag-bearing migrator making the transcontinental journey is, by weight, equivalent to a half-raisin carrying three uncooked grains of rice.

> Researchers are tracking more than 400 tagged monarch butterflies as they fly toward winter colonies in central Mexico. The maps [in the article] follow six butterflies. [...] Tracking the world's most famous insect migration may also have a big social impact, with monarch lovers able to follow the progress of individual butterflies on the free app, called Project Monarch Science. Many of the butterflies are flying over cities and suburbs where pollinator gardens are increasingly popular. Some tracks could even lead to the discovery of new winter hideaways.
"There's nothing that's not amazing about this," said Cheryl Schultz, a butterfly scientist at Washington State University and the senior author of [2]a recent study documenting a 22 percent drop in butterfly abundance in North America over a recent 20-year period. "Now we will have answers that could help us turn the tide for these bugs."

Soon y'all will have one injected so that the government can help you when you're in need.
At 60 milligrams, there will be no liquid involved at all, nor risk of deadly autism.

Listen to your chieftain's health advisories, "there's so much liquid" the babes are literally drowning in it while getting autistic.
The Commies did one thing right, they had drier vaccines.
Therefore almost no risk of baby drowning, and 120% less autism.

Not who or what I would choose to track, but whatever floats your boat I guess.
