Pollinators and Pollination

Plants rely on many partners in the task of moving pollen around to propagate themselves. The food chain and life itself on Earth relies on the partnership of plants and pollinators. Pollinators include bees, wasps, flies, moths, butterflies, ants, and birds. The most effective pollinators in general are bees. Pollen is a food source for bees that they collect and move with the assistance of hairs and other features of their bodies. We often think of honey bees (which are non-native) doing this job, but our native bees are primary pollinators.

Become a OSU Dandelion Detective
Dandelion Detectives is a STEM activity targeting 3-7 graders where participants work together to measure the value of weeds for insects. Dandelion Detectives will take place over the summer of 2021. Participants can be located in Ohio or surrounding midwestern states. 

Pollinators Matter

Ways we can thing about pollinators:

  • Curiosity about pollinators themselves... appreciation and support of bees, butterflies, birds, etc.

  • Curiosity about plants themselves... appreciation and support of one or more kinds of plants

  • Ecosystem services... (click here for a chart)

    • Tending toward (human) self-interest: Pollination, Food, Biodiversity, Aesthetics

    • Tending toward human care of nature: Stewardship, Habitat, Sustainability

Of the foods and beverages that we consume daily, over 30% rely on or benefit from a pollinator.

From Pollinator Partnership:

Somewhere between 75% and 95% of all flowering plants on the earth need help with pollination – they need pollinators. Pollinators provide pollination services to over 180,000 different plant species and more than 1200 crops. That means that 1 out of every three bites of food you eat is there because of pollinators . If we want to talk dollars and cents, pollinators add 217 billion dollars to the global economy , and honey bees alone are responsible for between 1.2 and 5.4 billion dollars in agricultural productivity in the United States. In addition to the food that we eat, pollinators support healthy ecosystems that clean the air, stabilize soils, protect from severe weather, and support other wildlife .

Gardening for Pollinators

Gardening for pollinators involves more than flowering plants. It is about habitat... food, shelter, water, and resources for reproduction. Pollinators have evolved to co-exist with particular plants and conditions. Butterflies and moths need specific plants that their caterpillars can eat. Bees require flowers that produce pollen as well as nectar and places to lay eggs (crevices, loose soil, tunnels) . Hummingbirds tend to visit flowers with particular shapes. Some cultivars of plants have blooms that physically make the flower unusable for pollinators. The structure of the flower may make access to nectar and pollen impossible, the flower may lack pollen or nectar, or a change in color may make the flower unrecognizable to a pollinator. Native plants are very important for pollinator gardening (that does not mean you have to give up all your non-native plants).

When people think of pollinator gardens, they typically imagine a place full butterflies. Remember that such gardens will have many types of visitors including bees, wasps, and flies (learn the differences). This is not a bad thing, but may require a shift in attitudes. Bees and wasps are most aggressive when they have something to protect...a nest or themselves. When foraging they are away from their nest and unless directly threatened they want to get about their business. And there are a wide variety of flies beyond house flies.
