I looked at the FAQ, tried to access "Garden Beans", but was unable to
access the web site...

I am growing runner beans for the first time for quite a few years, have
plenty of flowers, but up to now only one tiny bean has "set".
The atrocious weather this week has slowed growth anyway.

Some of the flowers appear to have been neatly nipped off, or else
dropped off for some reason, and I remember having this frustrating
problem on previous crops, i.e. - losing the first few pods at least.

The leaves have also been eaten away to some extent, but I was only able
to find a tiny black caterpillar on one, and I do use slug pellets when
the weather is damp.
I'm sure there is a well known cause of this...
