Unexpected Visitor

It's time to pop open a bottle of champagne and do a happy dance. Finally, finally, we saw a yellow-faced bumble bee (Bombus vosnesenskii) in our yard. After a 20-year absence.

Two Nectar Robbers

September 9, 2009

Golden Moments

September 7, 2009
Don't know if silence is GOLDEN, but Italian honey bees definitely are. Early morning Saturday, I watched a bee the color of liquid gold nectaring the lavender in our yard. A golden opportunity to capture her brilliance. She won't live long.

Day Visitor

September 4, 2009
Carpenter bees (Xylocopata tabaniformis orpifex) can't get enough of the day lilies in our yard. In the early morning, they buzz into the patch of day lilies to forage for nectar and pollen. When they're finished, it's easy to tell where they've been: they're covered with telltale yellow pollen.
