Mosquitoes bite. Their bites make us itchy. They make an annoying whining sound. Most people hate them. But mosquitoes are also pollinators. Pollinators help plants to grow. Orchids and goldenrods need pollination by mosquitoes to survive. Like butterflies, the elephant mosquito carries pollen from flower to flower.

Hummingbirds are amazing! They can hover, fly up and down, and they are the only bird to fly backwards. Their wings flap 50 to 60 times each second creating the humming noise for which they are named. Hummingbirds are native to the Americas. They pollinate honeysuckle, the morning glory, blueberry flowers, and an array of other trumpet-shaped native plants. Native Pollinators: Hummingbirds is a good place to start learning about these energetic pollinators....
