Should I release my butterflies if it's raining?

Butterflies do best when released on warm sunny days below 90 degrees Fahrenheit, so we recommend you not begin your butterfly project until the weather is consistently nice. However, we know that Mother Nature sometimes can surprise us. If it is raining for the foreseeable future (and its above 55 degrees), wait for a break in the rain before letting your butterflies go. They will be able to find shelter.
