Bees as pollinators Write in first row of chart Sweet Clover Alfalfa Garden Flowers Cosmos Sunflower Bees collect nectar and pollen from flowers. The pollen, from the stamen, sticks to the hairs of the bees body. When bees go from flower to flower, some of the pollen sticks to the stigma. Bees are most attracted to flowers that produce nectar. Bees are drawn to flowers that have unique petal colors and shape. Flowers that are in clusters are most likely to attract bees. This is because the more flowers, the more nectar!

Beetles as pollinators Write in 2nd row of chart Magnolia Gold rod Lily pad Flower Flowers that beetles like have a spicy, fruity or fermented odors. Because they are clumsy, the flower usually has a wide opening and are bowl shaped. These flowers are moderate nectar producers. Beetles are one of the first pollinators (dating back a million years ago) They rely on their sense of smell. Beetles are clumsy and need support.

Birds as pollinators Write in 3rd row of chart Honeysuckle Cardinal Flower Spiderhunter Hummingbird Purple Foxglove Sunbird Honeyeaters The flowers are tubular, funnel, or cupped. They are usually odorless flowers. Strong supports for perching. They have bright colors such as red, yellow, and orange.(Highly attracted to red). Birds that pollinate flowers have long-narrow beaks to reach nectar. While they have poor smell, they have excellent sight. When the birds put their heads in the flower, pollen collects on their heads and back.

Butterflies as pollinators Write in 4th row of chart Milkweed Butterfly Bush Aster Daylily Sage Flower Butterflies have a coiled tongue (proboscis) They collect pollen on their body as they go to flower to flower. Unlike bees, butterflies are able to travel long distances. This spread the pollen much greater distances. Butterflies choose flowers that are rich in pollen and nectar. They are attracted to white, pink, purple, red, yellow, and orange flowers. The flowers are usually umbrella shaped and have large petals

Flies as pollinators Write in 5th row of chart Corpse Flower Dutchman’s Pipe Carrion Flowers Flies will land on flowers for their nectar and pollen. Flies are decomposers and are attracted to the smell of rotting meat. There are certain flowers that emit this odor. Some flies also use flowers to lay their eggs. The Corpse Flower, the Dutchman’s Pipe and Carrion Flowers emit a strong odor Similar to decaying meat.

Bats as pollinators Write in 6th row Tricanthera Flower Banana Flower Cacao Tree Flower (Chocolate) Bats that pollinate are tropical or dessert bats They feed on insects in the flowers as well as the nectar and pollen. As bat go to different flowers, the pollen will stick to their faces. They have long tongues in order to reach the nectar. Over 300 fruits depend on bats as pollinators (mangoes, bananas, guavas). The flowers are nocturnal (open at night). They are usually large and are bell shaped. They can have a fruity or rotten odor. Some scientists believe that flowers have evolved to attract bats.
