  2. ALE 1 (Think, pair, share ~10 min) Compare and contrast Trichoptera with: Think: wings, antennae, mouthparts…

  5. ALE 3 • Watch the video about monarch larvae • What’s unique about the plant that monarchs feed on? http://youtu.be/cll2vGF04XI

  6. 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?
