We have often wondered why we get so many bees when there are so many other plants they could visit.
A recent article in Science magazine answers our question. Coffee flowers have a caffeine content equal to the caffeine in brewed coffee. Caffeine is a memory enhancer for honeybees. “Honeybees rewarded with caffeine, which occurs naturally in nectar of Coffea and Citrus species, were three times as likely to remember a learned floral scent as were honeybees rewarded with sucrose alone.”
Now we know. Bees are getting buzzed on caffeine.
