Below 32 degrees

[Turtlehead]

Can a Monarch be released when the night temperature will be below 32 degrees?

Thank you.

As day time temps are above 55 and the wings are dry. They can withstand temps below freezing, but not for periods of more than 3 days and not when they are wet, too.

Thank you so very much for the information. This is my first year raising and tagging monarchs.
