First Release of 2023

Advice for releasing your monarch butterfly

MichaelStephenWills

We let our first monarch butterfly rest overnight, until noon of the following day.

Pam did better with tracking the monarch’s flight, so I used video. Thanks Pam!

I delay butterfly release when:

  • the forecasted high temp is below 65° F (18° C) or 60° F (16° C) if sunny and calm.  When no other option exists, 50-59° F and sunny is borderline acceptable.
  • the forecast calls for rain.  A light rain is not a problem for butterflies with day-old dry wings, but it’s not a good release option for first-day newborns.
  • the butterfly emerges too late in the day.  I keep it overnight if the butterfly cannot get 3 hours warming of flight muscles in the sun.
  • there are storms in the forecast.  I wait when there are less than four (4) hours of good weather projected.  When extreme weather (like a hurricane) is forecast within twenty four (24) hours, I keep the butterfly safe until the storm passes.  Twenty four (24) or more hours should provide ample time to find shelter from the storm.
  • I am not sure about a release.  Keeping a butterfly overnight is acceptable. In fact, a butterfly’s wings are stronger on day two (2), providing better capability to escape predators.  A butterfly can easily hang from the mesh cage roof overnight. I do not worry about feeding a butterfly unless a second night of shelter is necessary.

As the moment of emergence approaches, the skin of a Monarch chrysalis becomes translucent to reveal the butterfly compressed into that small space.

  1. They are beautiful butterflies, Michael. I have never seen any in my immediate area, probably not enough milkweed about and way too dry in summer. Thank you for raising them up and releasing them.
