Ken Ramirez, a world-renowned animal trainer, was offered quite the challenge. A botanical specialty group in the United Kingdom had built a large garden in the midst of some tall buildings in London—a garden that was home to thousands of butterflies of varying species, as well as many other types of flora and fauna. Its purpose: to show the “symbiotic relationship between plants and animals,” wrote Ramirez, describing the task ahead. “The director of the project, Lucinda Bartholomew, had envisioned a fundraising gala presentation that would include an orchestra in the middle of the garden playing beautiful classical music while butterflies flew from one part of the garden to the other.” They wouldn’t just fly willy-nilly, mind you. The idea was to design and implement a plan to train more than 10,000 butterflies to traverse the garden, on cue, in unison. Now if someone offered me an assignment that seemed like an impossibility, I’d think long and hard about it. But the fact that Ramirez hadn’t ever worked with butterflies before and knew little about their sensory mechanisms didn’t deter him at all. Ensured help from the group’s butterfly experts, he enthusiastically agreed. ”What a unique training opportunity!,” he wrote.
