In a community garden in central St. Louis, Saint Louis University biologist Gerardo Camilo walked methodically, scanning the plants while holding a butterfly net. Then, he stopped and stared intently at a patch of impatiens.
He was pursuing a bee that was weaving in between the stems of the flowers. In one fell swoop, he swung the net down and clutched the net with a fist to trap the bee inside. He examined his captive with a quizzical expression.
"Wow! I have never seen this in my life," Camilo said. "What the hell are you?"
Camilo and other scientists have found that bee populations are abundant and very diverse in urban areas, compared to rural areas, a finding that could help save endangered bees, important pollinators.
