My Bumblebee Buzz pollination Videos

#1 -Common Eastern Bumblebees (Bombus impatiens) buzz pollinating wild senna (Senna marilandica) (above) These flowers don't produce any nectar. The high pitched buzzing vibrates the pollen out of the brown, tubular anthers in these flowers. Only bumblebees can successfully pollinate these meadow flowers, introduced European honeybees don't know how.

#2 - Common Eastern Bumblebees (Bombus impatiens) cleaning pollens from wild senna (Senna marilandica) and packing it into the pollen baskest on her rear legs (below) 

 

#3- A Brown-belted bumblebee (Bombus griseocolis) colleting pollen from shrubby St.John's wort (Hypericum prolificum) flowers. These flowers don't produce any nectar so the reward for visiting pollinators is only the nutritious pollen which bees feed to their babies. It is a good source of pollen and lipids. (below)
