Meghan Bennett, a Ph.D., student studying the alfalfa leafcutting bee (Megachile rotundata), was interested in how the bees time their emergence from their nest cells. She needed to record exactly what time the bees emerge in relation to different environmental cues. But collecting this kind of data requires watching nest cells (or videos of nest cells) and carefully noting time of emergence. It’s tedious and time-consuming, and one person can only watch so many cells at a time. She had a problem—an engineering problem.
