Some bees and insects have even developed specific body shapes and traits to pollinate certain flowers. Pollinators evolved alongside these plants over millennia, so they rely on a wide variety of blooms in your garden year-round for their food. Plants evolved with differing flower times, so they require pollination at different times of the year. Pollination occurs during spring, summer, and fall. In fact, one-third of all our food is the direct result of pollination by insects. Without robust colonies of pollinators – and especially bees who outwork every other pollinator – we’d see far fewer flowers in spring and summer and have far less food to eat. This fertilizes the flower, which later produces fruit and seeds. There it rubs against the female part of the flower, known as the stigma. The pollinator carries the pollen on its body within the same flower or to a nearby flower of the same species. How are plants pollinated by insects and bees?ĭuring a plant’s reproductive phase, a pollinator rubs against the pollen-rich male part of a flower called the anther. Here, we’ll focus on insects and bees and the flowers that attract them (native trees and shrubs are also sources of pollen and nectar for pollinators). Besides bees, plants are also pollinated by wind, gravity, water, flies, butterflies, birds, bats, moths, beetles, and wasps. New York Aster is native to Eastern North America and is a favorite of native bees.īy now, every gardener is aware – and hopefully non-gardeners too – that bees are essential for pollinating flowers and other plants, including many food crops.
