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 in the genus Pterostylis have been found to attract male fungus gnats with chemical attractants and then trap them using a mobile petal lip. [2] The general observation of insects being trapped and aiding pollination were made as early as 1872 by Thomas Frederic Cheeseman [ 3 ] and did not go unnoticed by Charles Darwin who examined the ...
The special fragrance collection organs are seen on the large hind legs of this Euglossa viridissima as it sleeps on a leaf. Male orchid bees have uniquely modified legs which are used to collect and store different volatile compounds (often esters) throughout their lives, primarily from orchids in the subtribes Stanhopeinae and Catasetinae, where all species are exclusively pollinated by ...
Flowers of plants in the genus Rafflesia (family Rafflesiaceae) emit an odor to attract the flies that pollinate the plant. The world's largest single bloom is that of R. arnoldii. This rare flower is found in the rainforests of Borneo and Sumatra. It can grow to be 90 centimetres (3 ft) across and can weigh up to 7 kilograms (15 lb).
The orchid family is one of the largest flowering plant families in the world. Orchids can be found on every continent except Antarctica, from the steamy jungles of Asia to the dry deserts of ...
The orchid uses scent to attract male wasps which pollinate the flowers as they attempt to mate with them. The scent released by the flowers mimic female sexual pheromones. [9] Both of the wasp species which pollinate fly orchids in the UK feed on Umbellifer flowers as adults and on froghopper nymphs as larvae.
The uptake of pheromone precursors from plants is also known for certain species of orchid bees and peacock flies. Male bees collect a mixture of terpenoids from orchids and use them as an aggregation pheromone to form lek mating. Sometimes the plant constituents control the development of the pheromone glands of male butterflies. [48]
