How to keep wild caterpillars as pets
Wait for the right season to go looking for caterpillars.
Caterpillars need specific weather and seasonal conditions before they can be found. You'll need to wait for warm weather and summer months before you can begin searching for your caterpillar.
The month of june is the ideal time to begin your search, as caterpillars will just start to be active during this time. If you wait too long, caterpillars may already be in their pupa or butterfly stages of life.
