A bumblebee on Stiff Coreopsis, Coreopsis palmata.
Same plant but this stem fell out into the grass. This is a sweat bee so named because they attracted to the salt in your sweat and sometimes land on you to collect it. Personally I've never had this happen though.
A honeybee on the yellow form of Butterflyweed, Asclepias tuberosa
A bumblebee on the same plant.
Here some other type of bee is on the plant.
Annual Sunflowers, Helianthus annuus
Great Coneflower, Rudbeckia maxima
, getting more attention than other Rudbeckia
plants I grow.
Even tiny bees seem to enjoy the odd shaped flower heads.
