Is your incoming weather forecast OK to release butterflies in? Is it too cold? Too windy? Too rainy? To answer that question, let’s consider all of the factors that can affect a butterfly when it is released:
1) Temperature
2) Rain
3) Light
After all of the meticulous planning that you’ve undoubtedly undergone, we’re sure you’re excited and ready to release your butterflies. But don’t get too carried away! You want to release it at the best time for the creature’s own safety as well.
Temperature
Ideal release temperatures are above 70 degrees although they can be released down to 60 degrees.
Butterflies are cold-blooded critters. Few can fly in temperatures below 60 degrees. If they must be released in cooler weather, it is best to place the butterfly underneath the end of a low tree limb, as high as you can reach. This keeps them out of the reach of ground predators such as ants. It protects them from rain and wind.
Although some species of butterflies will live through freezing temperatures, they do not fly when it is cold. If they are wet in freezing temperatures, they will die.
Rain
If it is raining too much for you to want to stand in it, don’t release butterflies in it.
Rain doesn’t harm butterflies. They live through storms. But they rarely fly in heavy rain. Instead, they land and wait for the rain to stop and for their bodies to dry before they fly again.
If you MUST release in the rain, do the same as for low temperatures. Place them underneath the end of a low tree limb, as high as you can reach.
Light
Release an hour before sunset if possible.
Although they can be released thirty minutes before sunset, their chance of survival is greater if they are released an hour before sunset. When it is dusk or dark, they sit and wait for sunshine.
If you MUST release in the dark, do the same as for low temperatures. Place them underneath the end of a low tree limb, as high as you can reach.
Be Advised
If the temperature, light, and other factors are not conductive for releases, chances are that they will land on the ground where people will step on them. Even if people are careful, they often pick up butterflies to move them to a safer location. Unless people know how to pick handle butterflies, they can mishandle them, causing fatal injuries.
The butterflies you release should be released where there is grass or plants. Concrete and roads are not safe release areas.
