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?
