Lynn,
The first varmint is a bag worm feeding on evergreen needles. They can infest a tree, shrub, or other large plant where the eggs over-winter. Here is a good link which explains better that I can:
http://www2.ca.uky.edu/entomol... This site covers them pretty well since it is by by M.F. Potter and L.H. Townsend, Extension Entomologists, University of Kentucky College of Agriculture. I like to spray at least once in early spring to eradicate hatching eggs. Then I spot spray whenever I see one.
The last one is an iris borer which begins its life cycle above ground as an egg from the iris borer moth. They also hatch in early spring and eat their way into the leaves and downward into the rhizome like in the picture. They can do a lot of damage if left to multiply uncontrolled. Here are some additional pictures; maybe they will show a little better detail. Hope this is useful.
