Thanks, David, for bringing me up to speed on Sepsidae flies. I had 
noticed them on the crocus flowers, so small and holding their wings 
oddly. Have not seen any paper wasps yet.
Apparently crocus flowers don't produce much pollen the first year. 
We have one clump, planted last fall, to which honey bees pay little attention.
