Honeydew is a sugar-rich sticky liquid, secreted by aphids, some scale insects, and many other true bugs and some other insects as they feed on plant sap. When their mouthpart penetrates the phloem , the sugary, high-pressure liquid is forced out of the anus of the insects, allowing them to rapidly process the large volume of sap required to ...
The upper portion of the inflorescence has a series of white, yellowish, or rusty urn-shaped flowers that face downward. [9] Each flower may have five sepals surrounding the base of the flower, [6] which measure 4–6 millimeters long and are 2—3 millimeters wide. [4] The fused petals (the corolla) measure 6–9 millimeters in length. [6]
Many orchids, including Angraecum sesquipedale, are pollinated by nocturnal butterflies and, as a result, tend to have light-colored or nearly white flowers that emit fragrance in the evening or night. Other examples of such orchids include Bonatea speciosa, Habenaria epipactidea, species in the genus Satyrium, Disa cooperi and D. ophrydea. [12]
Chiloschista phyllorhiza, commonly known as the white starfish orchid, [2] is a species of leafless epiphytic or lithophytic orchid that forms small clumps with many radiating, flattened green roots. A large number of short-lived, crystalline white, star-shaped flowers with a yellow labellum are arranged along thin, arching flowering stems.
Woolly aphids feed by inserting their needle-like mouthparts into plant tissue to withdraw sap. They are able to feed on leaves, buds, bark, and even the roots of the plant. As a result of feeding on the sap, woolly aphids produce a sticky substance known as honeydew, which can lead to sooty mold on the plant.
Most orchids have waxy pollinia. These are connected to one or two elongate stipes, [clarification needed] [3] which in turn are attached to a sticky viscidium, a disc-shaped structure that sticks to a visiting insect. [2] Some orchid genera have mealy pollinia. These are tapering into a caudicle (stalk), attached to the viscidium.
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 ...
