Today was not such a nice day, windy, drizzly, 17 degrees but not feeling warm. Despite this a Small white butterfly emerged from her pupa/chrysalis this morning. She was in a sheltered place and I kept an eye on her all day and she made her maiden flight eventually around 4.40pm, we had a break in cloud and saw the first sunshine of the day.
Now the question
When butterflies and moths are ready to leave the pupa do they do so regardless of the weather?
I was surprised how yellow a fresh specimen is.
