Pollination by flies, known as myophily, is the second most prevalent method of pollination among orchids, involving pollinators from twenty different dipteran families. [13] These flowers typically emit scents reminiscent of decaying organic materials, excrement, or carrion, which attract flies seeking food or suitable sites for egg deposition ...
Neotropical orchids themselves often exhibit elaborate adaptations involving highly specific placement of pollen packets on the bodies of the male orchid bees; the specificity of their placement ensures that cross-pollination only occurs between orchids of the same species. Different orchid bee males are attracted to different chemicals, so ...
The male collects fragrances from orchid flowers, which it stores in hollows in its hind legs. Orchids can be deceptive by mimicking the form of a female and her sex pheromone, thus luring male bees or wasps. [2] Pollination will take place as the males attempt to mate with the labellum, or the tip petal of the flower. [3]
Ophrys apifera, known in Europe as the bee orchid, is a perennial herbaceous plant of the genus Ophrys, in the family of Orchidaceae. It serves as an example of sexually deceptive pollination and floral mimicry, a highly selective and highly evolved plant–pollinator relationship.
Euglossa cordata is a primitively eusocial orchid bee of the American tropics. [2] The species is known for its green body color and ability to fly distances of over 50 km. Males mostly disperse and leave their home nests, while females have been observed to possess philopatric behavior. [3]
The knobs lead to a spout (see the Coryanthes leucocorys picture), but as the bee is trying to escape, the spout constricts. At that same moment, the small packets containing the pollen of the orchid get pressed against the thorax of the bee. However, the glue on the pollen packets does not set immediately, so the orchid keeps the bee trapped ...
Species of this genus are known to pollinate orchids and tamarillo plants, as well as a number of other flowering plants. [citation needed] Euglossine bees are of great ecological importance to a number of orchids for which they are the sole pollinators. [2] Information is needed on which species of orchid in particular is visited by E. mixta.
Bees in the Euglossini tribe, including Eulaema meriana, are known to pollinate these flowers supposedly because the orchids can deceptively mimic the form of a female and her sex pheromone. [6] When the bee touches down on the flower, a great effort is made to collect chemical scent - he eventually slides on the waxy surface of the hypochile ...
