Bees Cannot Do It Alone

In the absence of pollinators,

the whole agricultural sector would collapse, seriously endangering global food security. Pretty much all the seed plants we know need pollination to reproduce. The majority of flowering plants and coniferous trees would not exist without this process. Even though honeybees generally get the most credit for distributing pollen of many plant species, a variety of other pollinators do the same job as well. It is estimated that almost every fruit grown in the United States exists because of variety of pollinators like wild bees, flies, beetles, moths, bat, and other small animals¹. Let’s have a look together at some important pollinators you maybe didn’t know about.
 

    • Hummingbirds

Hummingbirds are the main pollinators of many native flower species in the Americas. Their pollinating services are especially important in the tropics where the majority of them live. They have great eyesight and use it to search for flowers that blossom in shades of red or have a trumpet-like shape. Some examples of their favorite flowers are mandevillas, the peacock orchid, the wild bergamont, the native coral honeysuckle, and the cardinal flower². They feed by reaching their long thin beaks into flowers to get the nectar, and while feeding, pollen gets attached to the feathers around their face. Hummingbirds are diligent pollinators, since they search for food most of the day and visit many different flowers.
 

    • Butterflies

The presence of butterflies in our parks and gardens makes the place aesthetically beautiful, and gives us a feeling of booming with life. And it’s not just a feeling, these colorful insects even facilitate flowers’ reproduction by carrying pollen on their bodies. Compared with bees, butterflies are not capable of distributing pollen between plants in large amounts, particularly because of their anatomy. Their bodies are very slick, making it difficult for pollen to stick on them, while butterflies’ long legs often do not allow for direct contact between their body and the pollen-bearing anthers. Butterflies can be found on clusters of flat, large flowers that are a rich source of nectar for them, such as coneflowers or zinnias³.
 

    • Ants

By visiting flowers to feed on energy-giving nectar, ants take the role of pollinators as well. Although, according to some scientists, their actions may even have negative effect. Some ants carry on the surface of their body chemicals which are destructive for pollen. Besides this problem, unlike their fellow pollinators with wings, they also cause a damage to flowers by crawling into them while trying to reach the nectar. Despite these issues, there are plants that have adapted to ant pollination through evolution. Perfect examples of this are the small stonecrop, the alpine nailwort and the cascade knotweed.
 

    • Black and white ruffed lemurs

The critically endangered black and white ruffed lemurs are in charge of the pollination of the traveler’s palm in rain forests of Eastern Madagascar. Lemurs, the largest pollinators on earth, have to open the flower bracts with their delicate hands to get the nectar. Then, while they feed on this sweet substance, pollen gets on the fur of their face and this way they carry it to the next flower. It has been suggested by scientists that this tree has evolved specifically to be pollinated by lemurs, as it requires manual dexterity to open its flowers, plus it offers an abundancy of nectar to meet their needs.
 

    • Honey possum

Honey possums are a cute pollinator species that can be found only in Western Australia. They specialize on feeding off the nectar and pollen of the banksia and eucalyptus flowers. These tiny marsupials display a few evolutionary adaptations to get the nectar from these trees. Their grasping feet with tail allow them to reach for flowers on thin branches, and their muzzle with a long tongue enables them to lick the nectar, while collecting and transporting pollen on their fur. Similarly, like in the case of lemurs, they are a perfect example of coevolution of plant species with their most efficient pollinators. Such strategy is key to the survival of a great variety of species on our planet.
