14 Odonata Dragonflies and Damselflies –2 pairs of long membranous wings. Wings are similar in size and shape. –Chewing mouth parts.

15 Mecoptera Scorpionflies –2 pairs of similar membranous wings –Chewing mouth parts

16 Hymenoptera Bees, wasps, and ants –2 pairs of membranous wings with reduced veination –Chewing or chewing and sucking mouth parts –Female has sawlike or peircing ovipositor or a stinger –Many live together in colonies

17 Plecoptera Stone flies –Have 2 pairs of membranous wings 1 st pair is long 2 nd pair is larger and folded in pleats Chewing mouth parts Cerci

18 Coleoptera Beetles –2 pairs of unlike wings 1 st pair meets in a straight line down the back 2 nd pair is membranous and folded under the front wings –Chewing mouth parts –No cerci

21 Thysanura Silverfish –Wingless –Chewing mouth parts –11 abdominal segments –Usually have long cerci

22 Review of Dichotomous Keys A dichotemous key is a guide for identification based on a series of steps with yes or no answers. –The answer at each step guides the user to the next appropriate step.
