Hunt’s bumble bee, Bombus huntii, a native to the intermountain west.
Hunt’s bumble bee is photographed here on the highly invasive weed, Houndstongue (Cynoglossum officinale). This plant is extremely mobile and once established out-competes native habitat. Because the seed is cased in the hard shell with barbs, it can last 7 to 10 years in the soil. (reference: Idaho Weed Awareness)
