Caught between a rock and a...soft place...
You'll often see tiny sweat bees nectaring rock purslane (Calandrinia grandiflora) in urban gardens. This plant, a native of Chile, brightens landscapes with its pinkish magenta blossoms.You probably wouldn't wear this color if you were in the federal witness protection program. It shouts "Look at me!"
The old saying that "it's so loud it could stop traffic" applies here.
It certainly stops insect traffic. (The lure, though, is the pollen, not the color.)
Last week we watched a tiny female sweat bee (Halictus tripartitus) nectaring the rock purslane.
Then she crawled to the lip of the flower, peered at her surroundings, and took flight.
