Cattleya cernua Cattleya cernua Cattleya cernua, commonly known as the Nodding Sophronitis, is a species of orchid occurring from Brazil to northeastern Argentina. It was the type species of the genus "Sophronitis" until the genus was made synonymous with "Cattleya". Twenty plants of "C. cernua" have received a total of 22 AOS awards. The described flowers range from 1.9 cm to 3.2 cm horizontal spread and from 2.0 cm to 3.0 cm vertical spread. In nature, "Cattleya cernua" is pollinated by hummingbirds drawn to the blooms' warm colors. The orchid's cryptic pollinia (masses of pollen which adhere together) provide an interesting adaptation
Flower constancy food resources and so will feed on a mixture of these to maximize their energy intake per unit time. As a result of this apparent contradiction, many hypotheses have been proposed to explain flower constancy in insects to determine the adaptability of flower constancy. One of the most popular explanations is that insects that are flower constant have limited memory space and can only focus on one flower type at a time. Insects, as with other animals, have short-term memory (STM) or "working memory" where information is stored temporarily for a few second or minutes. Additionally, insects have long-term memory
