Thanks Barry. Might be a good excuse for a nice walk.
Thanks for the posting Barry. MapMate tells me that the north Cardiff dot is at Southview, Tongwynlais, so I'll try and nip over there if I get chance.George
Checked the gromwell at Tongwynlais today - no larvae or feeding damage, but not surprising as there were only a few plants at the site.I did see a Clouded Yellow by way of compensation.
I noticed a fair amount of Common Gromwell in the Alun Valley this year whilst looking for butterflies. The grid ref was approx SS908758. Might be worth checking there?
