The first thing I want to start with is going to be Monarchs. Because they're the best ones to hatch from the chrysalis. First, you have to take milkweed and a stick and put it in a jar with cheesecloth on the top, elastic banded on, or a lid with nailed holes in it. Put the monarch caterpillar in the jar. And then put the lid on or cheesecloth.
Here's the picture of a monarch caterpillar and this is what it eats, the milkweed plant.
