Caterpillar Setups > Open Terrariums

The biggest enemy to butterfly caterpillars is their own waste or frass. It is important to provide sufficient airflow in open terrariums or open buckets to help caterpillar frass dry. It's also important to remove frass regularly. The advantage of terrariums over buckets is that it is easier to watch the caterpillars feed in a terrarium.

In a setup like this, it is important to place host plant cuttings in bottled of water, cork cuttings with facial tissue and place larvae on the host. Clean out frass regularly and replace host every five days or so.

Remember to keep open terrariums indoors and away from direct sunlight unless you are using potted plants with plenty of ventilation.
