I am used to seeing butterflies in my garden but in the last week have noticed an unusual concentration of painted lady butterflies. The usual butterfly population in my garden tends to consist of a mix of cabbage whites, small and large tortoiseshells, comma and peacock butterflies so I was wondering if there was a reason for this high concentration of painted ladies. This article just might explain it. It suggests that there is a mass migration of the butterflies this year with around 18,000 of them arriving on the north Norfolk coast from North Africa. Apparently the migration began last Thursday when large numbers of the butterflies were found in Dorset but since then they have been spotted pretty much everywhere. If you don’t know what one looks like, there is a picture on the left but chances are you could be seeing quite a lot of them this year.
