Update on the caterpillars....

The caterpillars ate and ate the brown stuff (it is called "nutrient") and grew double in their size. Then they attached themselves upside-down to the paper disk inside the lid.

Then I attached them to the inside of our butterfly cage so we could watch them form their crysallis. I was suprised at how little time it took for them to change! Now we are just watching and waiting for the first butterfly to appear!!
