Injured Butterfly, recovered butterfly

Came in from the garden and was doing veges for dinner when I felt something crawling up my neck. Reached up hurriedly with my hand and brushed it off   was sorry to see it was  a lovely little butterfly and my treatment had damaged it. I put it on a plant on the windowsill and opened the window but it never recovered. Just climbed up to the top of the plant and sat there.
 Am off down to my sons tomorrow so not much commenting for a day or two  as have to hot spot and I dont seem to  manage that way the same.
PS. Take note
Joy of joys I got up this morning to a recovered butterfly. Opened the window and it flew off
