Pollinators

Reviewed April 2025 | Written by: Grace Ferry and Brian Kunkel

What Pollinators Do For Us

  • Pollinators are critical to our food production system

  • More than 100 U.S.-grown crops rely on pollinators

  • The Honey Bee is our primary pollinator

    This native plant helps improve the ecosystem while also attracting native Lepidoptera pollinators.

        Other Native Pollinators:

        • Mason bees, Leaf cutters, Cuckoo bees.

        These pollinators all have different characteristics. For example, the Mason bee (Above, Osmia lignaria) is blue!

          Common Name: Red Necked False Blister Beetle

          Scientific Name: Asclera ruficollis

          Some pollinators come from the order Coleoptera. This beetle has hardened elytra, which is a major characteristic of Coleoptera. They are frequently found on flowers, because that is where they mate, and pollen is a big part of their diet. Be careful dealing with them, because they do have toxic defense chemicals.

           

          Ways to Promote Pollinator Activity

          • Plant native species

          • Avoid / limit pesticide use

          • Provide water and shelter
