Bumblebees

Today I was thinking about bumblebees, and the way they steal nectar from blueberry flowers.  Instead of trying to crawl into the flowers -- likely impossible, given relative size of flower versus bee -- they poke a hole near the base of the corolla, then suck up the nectar through the hole with their long tongues. 

One day back when I worked at Gray Herbarium, I wondered if I'd see this on old herbarium specimens.  So, I browsed thru some cabinets & pulled out a bunch of specimens, some over 100 years old.  Sure enough, at the base of almost every flower was that little hole.  Cool ol' bumblebees, stealing nectar for a hundred years.

In the autumn, you can pet bumblebees.  In the early morning of autumn days, you can often find male bumblebees hanging out on flowers.  They sleep there overnight, waiting for a chance to mate with later-arriving females.  Because they're still cold from the night, the bees are rather torpid.  Reach out a finger and stroke the fuzzy back of a bee!
