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 ...

Examples of pollinator-mediated selected traits could be those involving the size, shape, color and odor of flowers, corolla tube length and width, size of inflorescence, floral rewards and amount, nectar guides, and phenology. Since these types of traits are likely to be involved in attracting pollinators, they may very well be the result of ...
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, 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]
Hummingbird Phaethornis longirostris on an Etlingera inflorescence. 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.

A catkin or ament is a slim, cylindrical flower cluster (a spike), with inconspicuous or no petals, usually wind-pollinated (anemophilous) but sometimes insect-pollinated (as in Salix). It contains many, usually unisexual flowers, arranged closely along a central stem that is often drooping.
Insect pollinators preferentially visit flowers that are sexually viable and have not undergone color change. [7] Pollinators will learn and discriminate against floral stages from these signals benefiting both parties by allowing insects to be guided to flowers that are rewarding, while the flowers receive pollination.
