Oncidium papilio has the generic name in Greek for "butterfly appearance." The above flower is on top a nearly 3-feet stem and seeking to attract an insect for pollination. Simply, the plant has grown in the form of an insect to attract a sexual partner to continue its species. The slightest air movement will cause the stem and blossom to move in the manner of a butterfly. The white orchid to the lower right of the photograph will be seen in a future post. These are growing under an orange tree. A personal observation is that an orchid attracting a pollinator insect may flower with unusually large blossoms if placed near a dark background as the heavy foliage of an orange tree above. The flower wants a sexual encounter and can best be seen by a possible mate if blooming in good light. The exception to this is an orchid that does not depend upon its appearance to attract a pollination, but employs fragrance as a lure. If the attraction is an odor, the appearance of the bloom is not so important. The orchid attracting a particular fly in Central and South America blooms with the odor of decaying flesh of a dead animal. Those orchids are not necessarily known for their beauty by many of us, but the odor can be detected a mile away from the blooming plant.
