Caterpillars Day 3

It is so much fun to come out each morning and see how big these guys have grown.

This guy was only .5 cm, now he is about 1.5cm!
As the caterpillars grow, they must molt their skin.  Each stage is called an instar and there are 5 instars  before changing to chrysalis.  Here is a great link with more information.

Sophie wants to do her own nature blog, so I'll save some of the info for her to report on. This will be part of her science this year.
