Chrysalis

We looked at the chrysalises today and saw that one of them has some gold spots on it. So we looked it up in the book and found out that we think they use those to reflect off the sunlight so that when the birds fly by they know that it's not good to eat.

We could see a wing starting to form through the chrysalis. We have monarch chrysalises but there are other butterflys that looks almost exactly like it except for two black lines on the lower part of the bottom wings. This butterfly is called the viceroy. From a picture we saw that it's smaller than a monarch. We also learned that the monarch's colors proclaim to birds that it is distasteful so that is why the viceroy's colors are like the monarch's so that birds will leave it alone! I think the viceroy is just a big copycat!

  1. I think you are right - the Viceroy is just a big copy cat! What other animals do that? Can you think of another example?

  2. Yes, snakes! Red on yellow kill a fellow, red on black, venom lack. Coral and Scarlet King snake.
