How do you raise a black and orange fuzzy caterpillar?

Your caterpillar might be a woolly bear.

I set up a fish tank, that leaked, I put some dirt in the bottom and planted grass, weeds, and clover. Then I put in lots of different leaves and stood some sticks up so the caterpillar can have some place next summer to hang from while it spins it's cocoon. The caterpillar should go into hibernation, so put it in a very cold place for the winter. I put it in front of a window in a back room that stays just about as cold as it is outside in the winter. I water the plants a little when they need it and check to make sure it isn't too wet. My woolly bear is sleeping now, but next spring it will start eating and spin a cocoon. Then it will come out a moth. I can't wait.My woolly bear caterpillar's favorite food is clover and a weed that grows around here (Norton Shores, Michigan) that is 5 feet tall, but has small tender leaves and tiny pink flowers that don't ever open. I will have to wait until my caterpillar turns into a moth next spring and summer so I can tell you what it will like to eat as a moth.
