Another observation of mud-puddling by P napi, 5 of them this time, near
Markyate in N Hertfordshire, TL081178. Do P rapae ever do this? They were
very persistent, returning after I drove the car over their favoured spot.
Three of them were there an hour later, not mud-puddling though. Why do
they flutter their wings in an energy-wasting fashion? Could it be to
elbow the others aside?
