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 ...
Ophrys insectifera, the fly orchid, is a species of orchid and the type species of the genus Ophrys. It is remarkable as an example of the use of sexually deceptive pollination and floral mimicry, as well as a highly selective and highly evolved plant–pollinator relationship.
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 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 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]
Bulbophyllum nocturnum is believed to be the only species of orchid to routinely flower during the night. [2] Another species of orchid, Dendrobium amboinense , has been reported by some to open its flower at midnight and close them before noon, while other reports state that its flowers open at dawn.

Ophrys like other orchids are dependent on symbiotic fungi at some point during their life cycle, but especially for germination, which may take months or even years underground. Orchid roots contain Orchid mycorrhiza , coils of fungal hyphae inside orchid root cells.
Drakaea is a genus of 10 species in the plant family Orchidaceae commonly known as hammer orchids. All ten species occur only in the south-west of Western Australia . Hammer orchids are characterised by an insectoid labellum that is attached to a narrow, hinged stem, which holds it aloft.
