What are the Best Conditions for a Live Butterfly Release?
Releases should be scheduled during the daytime when the sun is out, or during overcast weather, but not when it is raining. Live butterflies should be released, at the latest, an hour or two before the sun sets to allow them time to acquire nectar and find a place to roost for the evening. The best temperature for the release of live Monarch butterflies is 62°F or higher, and for Painted Lady butterflies 72° F is required for them to take flight.
