British butterfly could be under threat from increasingly frequent episodes of extreme weather according to researcher data from the UK Butterfly Monitoring Scheme (UKBMS). The team found that rainfall level during the cocoon life stage affected more than a quarter of butterfly species in the UK. Aldina Franco from the University of East Anglia stated that this phenomenon comes out from over-wintering too early and subsequently be killed off by colder conditions.
Again, Franco stated that "years with extreme warm summers and winters may have mixed effects" She conduct a study to demonstrated previously unknown sensitivities of UK butterflies to extreme climate events, which are becoming more frequent with climate change. Otherwise, some of the climate effects are undoubtedly putting future populations at risk, such as warm winters. However, we have seen that warm and even climatically extreme hot summers may actually benefit butterflies."
