Broad-bordered Yellow Underwing

Hello,

I had few Broad-bordered Yellow Underwing pupae and was expecting an emergence in July, but two have already emerged. I had them in a greenhouse in the shade, so the daytime temperature is higher than outside at times, but it seems very early. I wondered if anyone had any insight as to whether it will be possible for them to survive until August/September from now. Seems unlikely to me, but maybe it's possible.

  1. They were out early last year (I had my first on 23rd June) so they may only need to hang around for three or four weeks!

  2. Do they breed during their first period of activity Dave? It seems strange to me that an adult moth, whose only purpose is to breed - am I being unfair on them? - has two periods of activity over so many weeks.

    Thanks for the reply by the way!
