Pollinators are a crucial part of the ecosystem and you can
encourage their presence by growing plants they like. To learn about some
pollinators native to the northwestern region of the U.S., read on.

Pacific Northwest Native Pollinators

Native northwest bees
are champion pollinators, buzzing as they move pollen from plant to plant in
early spring to late fall, ensuring the continued growth of a wide range of
flowering plants. Butterflies
aren’t as effective as bees, but they still have an important role to play and
they are especially drawn to plants with big, colorful blooms.

Bees

northern Washington to southern California. Common plant hosts include:

Sitka bumblebees are common in the coastal areas of the
western United States, from Alaska to California. They like to forage on:

  • Lupine
  • Rhododendrons

Van Dyke bumblebees have also been spotted in western
Montana and Idaho’s Sawtooth Mountains.

Yellow head bumblebees are common in Canada and the western United States, including Alaska. Also known as yellow-fronted bumblebees, this bee forages on geranium, penstemon, clover, and vetch.
