Dietary Needs of Pollinators and Other Beneficial Insects
Webinar Description:
Native insects have co-evolved with native plants that underpin their habitat. In a natural landscape the dietary needs of beneficial insects, such as pollinators and parasitoid/parasitic insects are met in whole or part by native plants. For example, monarch butterflies are nectar generalists that feed on nectar from both native and non-native species while their caterpillars are plant specialists that must feed on native milkweed species. As a second example, larvae of each bee species must be fed with a diet that includes pollen with a particular protein to lipid ratio. Each species of plant produces pollen with a unique protein to lipid ratio. In a diverse landscape native bees will collect pollen from a combination of species that provides the correct protein to lipid ratios. Finally, differences in floral structure arrangement and corolla size favor different pollinator species. By planting diverse meadows, we can support a broad array of pollinators.
