Hi Dennis,
One of the caterpillars is and Inchworm or Spanworm in the family Geometridae.  We are not sure of the exact species as there are numerous similar looking caterpillars posted to BugGuide.  We have a similar looking caterpillar that defoliates the new growth on our Matilija Poppy each spring.
