Hi John,

Mmm - I had thought that the Essex Skipper was doing pretty well
wherever I looked but I had just assumed that, as I wasn't doing it
very scientifically, I was just lucky! Essex has definitely been the
commoner of the two species when I have checked one out.

I don't know about the Small White - in south Oxon where I do most of
my field work there was quite a large flush of Small White though I
will have to go back to transect data to confirm this.
