A honey bee collecting nectar from an apricot flower.. The nectar resource in a given area depends on the kinds of flowering plants present and their blooming periods. Which kinds grow in an area depends on soil texture, soil pH, soil drainage, daily maximum and minimum temperatures, precipitation, extreme minimum winter temperature, and growing degre
A nectar spur is a hollow extension of a part of a flower. The spur may arise from various parts of the flower: the sepals, petals, or hypanthium, and often contain tissues that secrete nectar (nectaries). [1] [2] Nectar spurs are present in many clades across the angiosperms, and are often cited as an example of convergent evolution. [3]
Nectar is derived from Greek νέκταρ, the fabled drink of eternal life. [3] Some derive the word from νε- or νη- "not" plus κτα- or κτεν- "kill" [citation needed], meaning "unkillable", thus "immortal". The common use of the word "nectar" to refer to the "sweet liquid in flowers", is first recorded in AD 1600. [3]
A petal often consists of two parts: the upper broader part, similar to a leaf blade, also called the blade; and the lower narrower part, similar to a leaf petiole, called the claw, [3] separated from each other at the limb. Claws are distinctly developed in petals of some flowers of the family Brassicaceae, such as Erysimum cheiri.
A synthetically produced Nasonov pheromone can be used to attract a honey bee swarm to an unoccupied hive or a swarm-catching box. Synthetically produced Nasonov consists of citral and geraniol in a 2:1 ratio. The Nasonov gland was first described in 1882 by the Russian zoologist Nikolai Viktorovich Nasonov.
Nectar guides are markings or patterns seen in flowers of some angiosperm species, that guide pollinators to their rewards. Rewards commonly take the form of nectar , pollen , or both, but various plants produce oil, [ 1 ] resins, [ 2 ] scents , [ 3 ] or waxes.
An Australian painted lady (Vanessa kershawi) feeding on nectar through its long proboscis. In zoology, a nectarivore is an animal which derives its energy and nutrient requirements from a diet consisting mainly or exclusively of the sugar-rich nectar produced by flowering plants.
The brood pot will contain nectar and pollen similar to the bee bread in other bees; however, unlike other bees, the bee bread is the consistency of molasses instead of being solid. [7] The egg is laid on top of the bee bread and sealed in with wax, and the tunnel is partially filled with dirt to protect the egg. [ 8 ]
