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 ...
Orchids that attract Euglossine bees secrete scented oils, but while accessing these, the bees slip and into a water-filled bucket. To escape the bucket, the bee must crawl up a narrow tunnel, during which the plant attaches pollen sacs onto its back. The escaped bee will visit another orchid and drop the pollen, fertilising it.
Most are fly-pollinated, and attract hordes of flies. Bulbophyllum beccarii in bloom has been likened to smelling like a herd of dead elephants and both this species and Bulbophyllum fletcherianum are variously described as making it difficult to walk into a greenhouse in which they are being cultivated if the plants are in bloom because of ...
In this true mutualistic inter-relationship, both organisms gain benefits in their respective sexual reproduction - i.e. orchid flowers are pollinated and the Dacini fruit fly males are rewarded with a sex pheromone precursor or booster; and the floral synomones, also act as rewards to pollinators, are in the form of phenylpropanoids (e.g ...
The orchid species Epipactis veratrifolia mimics alarm pheromones of aphids to attract hover flies for pollination. [16] Another plant, the slipper orchid in southwest China, also achieves pollination by deceit by exploiting the innate yellow colour preference of syrphids. [17]
The small size of many flies is often made up for by their abundance, however they are unreliable pollinators as they may bear incompatible pollen, and lack of suitable breeding habitats may limit their activities. Some Pterostylis orchids are pollinated by midges unique to each species. Due to mutual specialisation, pollinators are highly ...
Cluster flies are distinct from other types of flies and are often confused with more common houseflies. They are about a quarter-inch long, with a grayish appearance and golden or silverish hairs ...
Orchids of the genus Bulbophyllum produce strongly scented flowers. The flowers produce various odors resembling sap, urine, blood, dung, carrion, and, in some species, fragrant fruity aromas. Most are fly-pollinated, and attract hordes of flies.
