Bombus

Bombus "a deep, hollow noise; a buzzing or booming sound," www.etymonline.com
 
Bombus sp. is the latin name for the genus of any of the 800 or so species of bumble bees that one could run into in the world.

The last few days in the Bella Coola Bella have been cool with a few showers. There was one day this week when it was just warm enough to get the bumble bees mobile.  It didn't take them long to find the few garden flowers that are out, because there aren't very many so far.  It's always nice to see these big guys return and start working over the plants and having the flower pollen stick to them so they will transfer it to some other deserving flower.   The guy in this photo had two buddies, but the trio wasn't any threat, because there just wasn't enough heat to let them get too revved up, so the most they could do was lazily crawl around the crocus and hope some rays hit them long enough to fly off to wherever they make their nest.  Grizzly
