Large White male - Pieris brassicae

Spotted in the garden in August (and onwards)  this is the Large White.  Quite often see them in pairs in the summer months (are they mating on the wing, then?) flitting around.  But until t this year never bothered to find out exactly what they were called - just knew the old fashioned name of cabbage white because the caterpillars love cabbage leaves.  And look!  brassicae in the name!
Well here is the male, so look out next summer.
