| Re: Clouded Yellow but which one?
Colias croceus- the common Clouded Yellow is the species normally encountered, though numbers vary from year to year as a basically immigrant species + this has been a good year for them. There is a helice version that can be confused with the extremely rare (in UK) Pale Clouded Yellow.
Berger's Clouded Yellow is even rarer + I can't remember when 1 was last claimed in the UK.
You will be extremely lucky to see any other than the first species mentioned here in the UK. |
