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 ...
Moths, like butterflies, bees and other more popularly recognized pollinating insects, serve an essential role as pollinators for many flowering plants, including species that bees do not visit. Nocturnal moths fly from flower to flower to feed on nectar during the night much as their diurnal relatives do during the day.
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 ...
Pollination systems are mostly mutualistic, meaning that the plant benefits from the pollinator's transport of male gametes and the pollinator benefits from a reward, such as pollen or nectar. [1] As nectar robbers receive the rewards without direct contact with the reproductive parts of the flower, their behaviour is easily assumed to be ...
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]
Many plants are diurnal or nocturnal in the opening and closing of their flowers. Most angiosperm plants are visited by various insects, so the flower adapts its phenology to the most effective pollinators. [11] For example, the baobab is pollinated by fruit bats and starts blooming in late afternoon; the flowers are dead within twenty-four ...
Many flowers and plants deemed safe for humans are toxic for cats, according to the American Society for the Prevention of Cruelty to Animals (ASPCA). So, before you buy flowers for your next big ...
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.
