This cavity is covered with a very adhesive substance to successfully retain the pollinium. The most fascinating aspect of the orchid is its flower, characterized by amazing shapes, sizes and colors. From their appearance we find similarities with people, animals, birds and insects. Regarding size, there are flowers ranging from two millimeters such as the Trizeuxis falcata, up to the 70 centimeters Phragmipedium caudatum, the largest flower in the species. Pollination is usually performed by bees, flies, butterflies and certain birds.
Some insects search for nectar, some for solid food while others seek oils and perfumes.
The male Euglossini bee seeks out the orchid flower to bask in its scent, with which they attract females. Apparently, for mutual benefit from these visits, orchids have developed their sexual structures to function with pollinator agents. These are pollinating mechanisms rather than tricks. Thanks to this mechanism, nearly 15 spots have been reported to catch the pollinarium, through the viscidium. Once the pollinium has adhered to the stigma by means of the pollinator, the formation of seeds begins.
