Can You Label the Larvae?
Monarch caterpillars grow through five stages. Each stage is called an "instar." This picture shows a monarch at each of the five instars.
The smallest stage is the "1st instar." Knowing that, can you name the others? Slide these names in place to label each larva. (Then peek here to see if you're right!)

3rd instar Try it!
