We’ve seen big declines in wild bee populations. That’s not just bad for the fuzzy little bees; it could drive up prices for almonds, blueberries, and other pollinator-dependent treats.

The challenge is knowing what would help them. Do we focus on preserving habitat and flowers? Or should we focus on certain pesticides? Is climate change behind this, too? It’s hard to say because bees are hard to study. It’s relatively easy to count long-legged pronghorns or wide-winged condors compared to counting the gnat-sized Perdita minima, the world’s tiniest bee.

That’s why a research team at the University of Missouri has been putting little microphones in alpine meadows. When those mics record buzzing, the team’s software analyzes the noise to tell scientists the number and species of bees visiting. They just published a paper, showing that their methods work.

This breakthrough could allow regular folks to collect solid scientific data from the safety of their porch. Farmers could “monitor pollination of their orchards and vegetable crops and head off pollination deficits,” said Candace Galen, a biological science professor who led the university’s research team, in a news release.

Interested? The group is working on an app that would let you collect bee data with your smartphone.
