In Warwickshire, the Clouded Yellow is an uncommon migrant but during 'Clouded Yellow' years where good weather and southerly winds combine, large numbers may be forced northwards from mainland Europe, through southern Britain into our region. In, Warwickshire like much of the the UK experienced large numbers of Clouded Yellows.
Migrant in Warwickshire.
Can be seen anywhere in the region, especially places where there is a plentiful supply of nectar. Red Clover fields are a good place to look.
A photographic slideshow displaying various images of the Clouded Yellow is currently in development.
