Huge Victoria Regia water lilies in one of the tributaries of the Amazon to Iquitos about 40 miles near the town of Indiana. The giant water lilies are distributed in the Amazon and other tropical aquatic regions. When grouped together, form a kind of floating miniature prairie. The most wonderful is Victoria amazonica, Amazon water lily. Measure up to four feet in diameter and is capable of supporting the weight of a small child. The Amazon lily is a peculiar pollination cycle. The giant flowers open at dusk at a rate easily detectable. The flowers produce a strong smell of candy, and trigger a stimulus that raises the temperature of the central flowering 11 above ambient. The fragrance combined with the heat, attracts beetles gather in the center of the flower. As the evening progresses, the flower closes, trapping inside the insects. At dawn, the flowers change to pink and beetles feed on the internal structures of the flower. At dusk, the flowers have become a dark reddish-purple color, open and covered with pollen beetles fly off to find another water lily. In doing so, carry pollen from flower and pollinate the first to the second.
