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, resins, scents, or waxes. Such patterns also are known as "pollen guides" and "honey guides", though some
13 Feb 2013 From the classic observations of Sprengel [1] to the discovery of UV nectar guides [2], [3] to modern work on the genetic architecture of floral pigmentation [4], researchers have largely focused on understanding how floral patterns promote pollinator visitation. For example, pollinator preferences for specific
These patterns are sometimes visible to humans; for instance, the Dalmatian toadflax (Linaria genistifolia) has yellow flowers with orange nectar guides. However, in some plants, such as sunflowers, they are visible only when viewed in ultraviolet light. Under ultraviolet, the flowers have a darker center, where the nectaries
1 Jul 2011 (g) Reflectance spectra for components of artificial flowers used in experiment; our colours mimic a natural situation in which foliage provides a grey-green background, flower petals are blue and nectar guide patterns are UV-blue. Photographs: A.S. Leonard. Often, it is assumed that floral patterns are
In many bee-pollinated flowers, there is a region of low ultraviolet reflectance near the center of each petal. This pattern is invisble to humans because our visual spectrum does not extend into the ultraviolet. Bees, however, can detect ultraviolet light. The contrasting ultraviolet pattern (called a nectar guide) helps a bee
27 Jul 2011 The most widespread cues consist of converging lines or dots, or a marking around the corolla opening [2]. These 'nectar guides', first described by Sprengel [1], generally contrast strongly with the rest of the corolla. In some cases this contrast occurs mainly in the ultraviolet (UV) spectrum, making the guide
25 Aug 2014 Well, the thing about nectar guides is that we humans can't always see what the bees do! We can see all of the colors from red to violet, but bees see a shifted spectrum from yellow through ultra-violet (UV). So to bees, even seemingly plain flowers may have bold nectar guide patterns.
