Cuckoo! Cuckoo! Cuckoo!

September 8, 2008
We've all heard of the cuckoo clock. And most of us have heard of the cuckoo bird (Cuculus canorus), which lays its eggs in the nest of birds of other species. But the cuckoo bee? Yes, there is a cuckoo bee. The female lays her eggs in the nests of other solitary nesting bees. They resemble wasps.

September 5, 2008

Gollywhoppers in Love

September 2, 2008
He didn't bring her flowers. They were already sharing a sunflower leaf. He didn't bring her candy. They'd already dined on nectar. It was Labor Day and the two crane flies looked quite friendly in our bee friendly garden. More than friendly. I think they were in love.
