The shapes, colors and fragrances of orchids are the result of their coevolution with pollinators. Pictured is a flower Coryanthes leucocorys, species that has evolved one of the most fascinating mechanisms of attracting pollinators by means of a liquid-filled pouch. Pollinia of an orchid of the genus Phalaenopsis in lateral view Pollinium of ...
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 until the glue has set. Once the glue has set, the bee is let free and he can now dry his wings and fly off.
Baltimore Checkerspot (Euphydryas phaeton) nectaring at daisy (Argyranthemum)Pollination syndromes are suites of flower traits that have evolved in response to natural selection imposed by different pollen vectors, which can be abiotic (wind and water) or biotic, such as birds, bees, flies, and so forth through a process called pollinator-mediated selection.
Dendrobium Orchid. There are as many as 1,800 different species of dendrobium orchids. These orchids like to grow in small pots and often have tall, top-heavy blooms that require staking for support.
Orchids are beautiful plants that can brighten any home in the middle of winter. But some people find them challenging to grow. A Stroll Through the Garden: Orchids can brighten a cold winter day
In winter, the optimal temperature range is between 26 and 27 °C and 15-17 °C at night. Significant temperature differences are beneficial to Paphiopedilum rothschildianum; the region of Mount Kinabalu to which it is endemic has noticeable temperature drops and fluctuations which has caused the orchid to become adapted to this habitat type.

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.
