Wear bright colors or floral patterns rather than plain dark clothing, since butterflies are attracted to color and pattern, and visitors in vivid outfits are far more likely to have one land on them. Move slowly and avoid sudden gestures, since butterflies sense air movement through tiny hairs on their bodies, and quick motions like clapping or swatting will startle them away before you get a close look. Never touch a butterfly's wings, even gently, since the wings are covered in delicate scales that rub off at the slightest touch, and losing enough scales can impair a butterfly's ability to fly. Check your clothes and bags carefully before leaving the exhibit, since butterflies often land on visitors unnoticed, and most facilities do a visual check at the exit specifically to prevent them from being accidentally carried outside. Avoid wearing strong perfume or cologne, since the scent can interfere with the pheromone signals butterflies use to find food and mates, making them less likely to approach you. Look for feeding stations with fruit or nectar rather than only watching butterflies in flight, since these areas offer the best chance to see butterflies up close for an extended time as they feed.
