Flower Constancy
Be a bee. Carry pollen from flower to flower of the same kind to set seed, and skip flowers with a smelly footprint.
Many bees show "flower constancy", sticking to one kind of flower per trip, which helps carry the right pollen to the right plant. Wikipedia Bumblebees leave a "smelly footprint" on flowers, so other bumblebees can tell a flower has just been emptied. BBCT Tap a flower to visit it. Visiting the same kind as your last flower pollinates it. A different kind wastes your pollen. Emptied flowers show a footprint for a few seconds.
