Butterflies exposed to the open night sky lose heat by radiation, so that they become colder than ambient temperature.  We knew from previous research what happens to dry butterflies, but we needed data on what happens to butterflies wet by rain or snow.  The coldest time of night is between 4am and 8am.  By starlight and with frozen fingers, we attached temperature probes to butterflies, misted them lightly with water, and recorded their temperatures as they reached equilibrium.
