Plants fall into pollination syndromes that reflect the type of pollinator being attracted. These are characteristics such as: overall flower size, the depth and width of the corolla, the color (including patterns called nectar guides that are visible only in ultraviolet light), the scent, amount of nectar, composition of nectar, etc. [2] For example, birds visit red flowers with long, narrow ...
Entomophily or insect pollination is a form of pollination whereby pollen of plants, especially but not only of flowering plants, is distributed by insects. Flowers pollinated by insects typically advertise themselves with bright colours, sometimes with conspicuous patterns (honey guides) leading to rewards of pollen and nectar ; they may also ...
Wind-pollinated flowers often have small, dull petals and produce little or no scent. Some of these flowers will often have no petals at all. Flowers that depend on wind pollination will produce large amounts of pollen because most of the pollen scattered by the wind tends to not reach other flowers. [15]
Entomophily, pollination by insects, often occurs on plants that have developed colored petals and a strong scent to attract insects such as bees, wasps, and occasionally ants (Hymenoptera), beetles , moths and butterflies (Lepidoptera), and flies . The existence of insect pollination dates back to the dinosaur era. [13]
Rewards commonly take the form of nectar, pollen, or both, but various plants produce oil, [1] resins, [2] scents, [3] or waxes. Such patterns also are known as "pollen guides" and "honey guides", though some authorities argue for the abandonment of such terms in favour of floral guides (see for example Dinkel & Lunau [4]).
Their flowers tend to be small and inconspicuous with many pollen grains and large, feathery stigmas to catch the pollen. However, this is relatively uncommon (only 2% of pollination is hydrophily) and most aquatic plants are insect-pollinated, with flowers that emerge into the air. Vallisneria is an example.

Ornithophily or bird pollination is the pollination of flowering plants by birds. This sometimes (but not always) coevolutionary association is derived from insect pollination ( entomophily ) and is particularly well developed in some parts of the world, especially in the tropics, Southern Africa, and on some island chains.

[9] [10] The flowers of coral trees are diadelphous and are considered papilionaceous, but the wings are much reduced, suggesting a flower with three petals. [1] [10] Their keel petals are elongate, fused together and sometimes tubular to facilitate pollination by certain bird groups, [10] while secondary compounds in their nectar seem to repel ...
