 have the scape dark, one has the labrum dark, one has no spots on face

 in certain lights, but there is no thickening. 



The female collects pollen of Boltonia asteroides. I regard it as an 

 oligotropic visitor of that plant, but the female may get pollen from some 

 other species of Compositse.
