Led by Chris Barnhill, the nursery manager at the Arboretum, eager butterfly seekers heard of ways to attract the delicate insects. Barnhill began the hour-long discussion going over the structure of a butterfly and its functions. Barnhill explained that a butterfly tastes with its feet and differs from a moth. While moths have feathery or straight antennae. Other differences Barnhill offered were that butterflies are diurnal, or fly during the day, and moths are nocturnal.
Butterflies also hold their wings together, vertically, over their backs.
Barnhill used his own arms to imitate how moths fold their wings horizontally over their backs. Barnhill asked as he rested his arms down from the wing demonstration. Audience members shook their heads, not knowing the answer. Barnhill said that during the medieval times, butterflies were thought to steal the cream from cows and then fly away. The name evolved from the color of the cream.
