Once you have setup your water bottles with caterpillars on plant, place them in a 5 gallon bucket. Make sure the lid has plenty of ventilation either by poking holes in it or cutting out a circular section and fastening netting over the lid.
You need to replace your parsley cuttings and remove all waste every four days or so to ensure that your caterpillars are getting fresh plant in a healthy environment. (This type of procedure becomes extremely critical when raising indra swallowtails; which will be reviewed in the Techniques by Taxa section.)
