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
Portia labiata the draglines of equal-sized females and then pitted some of them in contests. Other females avoided the draglines of the victors, and spent the majority of their time on draglines of the losers. Similar tests showed that females of "P. fimbriata" from Australia and "P. schultzi" from Kenya do not avoid draglines of a powerful fighter. In "P. labiata" and in some other species, contests between males usually last only 5 to 10 seconds, and only their legs make contact. When hunting, mature females of "P. labiata", "P. africana", "P. fimbriata" and "P. schultzi" emit olfactory signals that reduce the
