Caenurgia, Mocis and Ptichodis

We have a lot of these particular lesser underwings at the CB.  Chances are, a moth fooling around in the grass as Ogma's baleful eye glares down  is one of these.  Alas, they are a little hard to distinguish, one from another.  In particular, a couple of the Mocis are tough.  We are pondering some of the CB Mocis still.  Someday we may figure them out, fer sure.  Hocus, pocus is it Mocus or Ptichodis?  Huh-huh. 

These moths tend to feature horizontal stripes.  On this one, Caenurgia erechtea, one of the most photographed of all Norte Americana moths, the approximately horizontal stripes are bolder than average.
