The Clouded Yellow butterfly has only been recorded on one previous occasion so far this year, it is an immigrant originating from Southern Europe and North Africa so numbers occurring do fluctuate greatly, during a good year they can produce up to three broods.
A strong Westerly wind and cooler temperature overnight continues to influence low return on the moth traps.
