A chrysalis is a caterpillar that has entered the pupae stage, the stage during which it goes through a transition and turns into a butterfly. The chrysalides will usually be attached to a stick since the butterfly needs to be able to hang when it emerges. During this stage, your job is to keep the environment in the jar nice and moist so that the chrysalis won't dry out. Use a spray bottle to spritz inside the jar from time to time. The pupae stage lasts for several months, and during this time you won't see much activity, but rest assured that the pupa is alive and will eventually emerge. If you captured the caterpillar in the fall, it should emerge in time for spring. If the chrysalides are not attached to a stick, or not hanging in a spot where the butterflies will be able to stretch out, you'll need to move them to a better spot. If the butterflies emerge too close to the bottom of the jar, or in a cramped spot where they can't hang and stretch their wings, their wings won't properly form, and they won't be able to fly.  If a chrysalis is on a stick that's too close to the bottom of the jar; you can simply move the stick, so it's positioned in a better way. You could also tape the bottom of the stick to another stick to make it longer if you need to. The chrysalis should be positioned near the top of the jar, hanging from the underside of the stick. If the chrysalis is resting on the bottom of the jar; you need to attach it to a stick. Use a dab of slightly cooled hot glue to glue one edge of the chrysalis to the underside of a stick, then position the stick in a good spot. After several months, the chrysalides will begin to turn dark or clear, indicating it's time for the baby butterflies to come out. It only takes a few seconds for them to come out and begin stretching their wings. They'll hang from the underside of the stick and slowly move their wings, giving them time to harden. Again, if they don't have space for this essential process, their wings will never fully form, and they won't be able to...
