The Latin name for this one is Geranium pusillum and its common name is Small-flowered Cranesbill. The best image I could find to confirm this was from a wonderful botanical garden blog in...RUSSIA! So how did this little guy get in my garden and gardens all across the U.S.? Visit our wonderful host Lisa to see other mysteries at http://lisaschaos.com/ . It's a fun group!
By the way, our garden variety Geraniums aren't in the Geranium family! David/ Tropical Texana
The little bee or fly is extremely tiny...measured in millimeters!
Here's the leaf and actual size.
Thanks for stopping by.
