The existence of insect pollination dates back to the dinosaur era. [13] Insect pollinators such as honey bees (Apis spp.), [14] bumblebees (Bombus spp.), [15] [16] and butterflies (e.g., Thymelicus flavus) [17] have been observed to engage in flower constancy, which means they are more likely to transfer pollen to other conspecific plants. [18]
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 ...
Few plants self-pollinate without the aid of pollen vectors (such as wind or insects). The mechanism is seen most often in some legumes such as peanuts. In another legume, soybeans, the flowers open and remain receptive to insect cross pollination during the day. If this is not accomplished, the flowers self-pollinate as they are closing.
A pine with male flowers releasing pollen into the wind. Features of the wind-pollination syndrome include a lack of scent production, a lack of showy floral parts (resulting in small, inconspicuous flowers), reduced production of nectar, and the production of enormous numbers of pollen grains. [4]
The costa (C) is the leading marginal vein on most insects, although a small vein, the precosta, is sometimes found above the costa. In almost all extant insects, [1]: 41–42 the precosta is fused with the costa; the costa rarely ever branches because it is at the leading edge, which is associated at its base with the humeral plate. The ...
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.
