According to this article five species of rare butterflies could soon be extinct. The annual survey of butterfly numbers in the UK has found that overall butterfly numbers are much lower than average. The problem is the wet summers we have experienced in the past few years which make it difficult for the insects to breed. Another wet summer could mean that species such as the Duke of Burgundy, High Brown Fritillary, Wood White, Lulworth Skipper and the Pearl-bordered Fritillary will become extinct. It seems there is not much we can do to save them other than hope for a long dry summer.
