Class meeting Nov. 16th Objectives: 1. Compare and contrast Trichoptera and Lepidoptera with other insect orders 2. Evaluate the benefits and pitfalls of mimicry 3. Model a possible route of evolution of a defense mechanism
ALE 1 (Think, pair, share ~10 min) Compare and contrast Trichoptera with: Think: wings, antennae, mouthparts…
ALE 1 (Think, pair, share ~10 min) Morphological feature
ALE 2: Class discussion • What is the purpose of mimicry? • Who benefits? Who loses? Or is it a win-win deal?
ALE 3 • Watch the video about monarch larvae • What’s unique about the plant that monarchs feed on? http://youtu.be/cll2vGF04XI
ALE 3 • Watch the video about monarch larvae • What’s unique about the plant that monarchs feed on? • How can the larvae feed on the plant and not get poisoned themselves? • How did the monarchs evolve this ability? Make a diagram showing a possible sequence of events leading to evolution of this mechanism
