  1. Lab Quiz 11 Review • 10 questions (5 on order/family; 5 on order/family and species) • Study power points and lab quizzes 6, 7, 9, 10 • Study lab gallery, http://www.entomology.umn.edu/cues/4015/lab/photos.htm • Be familiar with orders, families, and selected species on the lab quizzes and in this slide show (families and species to know are in blue) • Recognize selected damage • Distinguish between caterpillars (order Lepidoptera) and sawfly larvae (order Hymenoptera)

  15. How to distinguish between caterpillars (order Lepidoptera) and sawfly larvae (order Hymenoptera) David Laughlin Caterpillars (top) have 2 to 5 pairs of prolegs, whereas sawfly larvae (bottom) have more than 5. Also, sawfly larvae lack crochets on their prolegs
