i. Oblique-banded Leafroller Moth, Choristoneura rosaceana on basswood leaf.  I'm less certain about the id of this one.  There are a number of green leafroller moths with black heads.  I arrived at my id by cross checking the food plant database at (a site dedicated to leafroller moths) with the range maps at Moth Photographers group.  This narrowed down the choices to about a dozen moths.  Then I compared photographs of the caterpillars to my photographs.  Even if I'm wrong about the id, it was a fun process!
