The summer of 2019 has provided a welcome boost to butterfly population levels, according to the latest results from the annual UK Butterfly Monitoring Scheme (UKBMS) led by Butterfly Conservation, the UK Centre for Ecology & Hydrology (UKCEH), British Trust for Ornithology (BTO) and Joint Nature Conservation Committee (JNCC).
In their best year since 1997, just over half of UK butterfly species showed higher population levels in 2019 compared with 2018, making it the 8th best year out of the 44-year series.
Butterflies most likely benefited from an unusually warm and wet summer conducive respectively to both a strong emergence of adults and successful development of the immature stages preceding this emergence. MORE
