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 ...
Eufriesea purpurata is a species of eusocial orchid bee common in northeastern South America, particularly in the Amazon basin. [1] [2] It is an important pollinator of various wild plants, and it is noted for its attraction to various synthetic compounds used by humans, including some insecticides.
The fragrant plant is pollinated by the typical Euglossini bees (an Eulaema species) These bees are part of what is probably the most complicated pollination scheme presently known in nature. [ 2 ] and has one of the largest orchid blooms, sometimes weighing up to 100 grams (3.5 ounces) [ 3 ] [ 4 ] and measuring up to five inches (12.5 ...

Orchid bees are considered to be key species in lowland forests because they are pollinators of specific tropical plants. [10] It is in fact the females that perform cross-pollination. [3] They have also been targets of conservation, and the diversity of the euglossine bees as a whole is being affected by habitat fragmentation. [10]
When an orchid bee pollinator lands on the opening of the flower, its weight tips the flower forwards, and the lip moves down to allow the bee inside the flower. Having moved into the flower, the change in the centre of gravity tips the flower back, flipping the lip upwards, pressing the bee against the rostellum and sticky pollinia .
Pollinators and orchids use the same chemical compounds in the same absolute amounts in their pheromones and allomones, respectively. [19] Every Ophrys orchid has its own pollinator insect and is completely dependent on this species for its survival. Duped males are less likely to return and may ignore other plants of the same species.
The male orchid bees (not the females) are attracted to the flower by a strong scent from aromatic oils, which they store in specialized spongy pouches inside their swollen hind legs, as they appear to use the scent in their courtship dances in order to attract females. The bees, trying to get the waxy substance containing the scent, sometimes ...
