Cinquefoil Masked Bee

Notes: This northern species persists in good numbers in the Northern and Western portions of its range (e.g., in Canada and the Rocky Mountains) but is rare and local at best in the Northeastern United States and may have declined at the southern edge of its range. Causes of a potential decline are unknown, but it is possible that reforestation of historically-denuded mountaintops in New England (and New York) led to a decline due to ecological succession of its host plant Potentilla .
