Brilliant Butterflies

Butterflies are in trouble and they need our help.

Many butterflies and insects are in serious trouble; the State of the UK’s Butterflies 2015 report evidenced that 76% of species have declined over the last 40 years. Brilliant Butterflies works to help change this. 

Since 2019 we have worked to restore a nationally rare habitat, chalk grassland, and create new habitat for butterflies and insects across nature reserves, road verges, and parks. 

Volunteer with us to help nature thrive, weekends and weekday sessions. Contact and our friendly team will be happy to hear from you!

Brilliant Butterflies has created new wildlife havens in the southern fringes of Croydon, Bromley and Sutton, providing refuges for pollinators and beautiful, tranquil pockets of chalk meadows. Our portfolio of new habitat is below.

Brilliant Butterflies is a partnership between London Wildlife Trust,  Natural History Museum and Butterfly Conservation, funded by a Dream Fund Award, thanks to players of People’s Postcode Lottery,

Why do butterflies need our help?

Many butterflies and insects are in serious trouble; The State of the UK’s Butterflies 2015 report evidenced that 76% of species have declined over the last 40 years. A Wildlife Trusts 2019 report, Action for Insects, indicates that the abundance of insects in Britain may have fallen by 50% or more since 1970.

Butterflies and other insects are highly sensitive indicators of the health of the environment and play crucial roles in the food chain as well as being pollinators of plants. 

How will Brilliant Butterflies help?

As well as providing vital homes for butterflies and insects, Brilliant Butterflies will capture vital monitoring data to help make a case for the future protection of the specialist sites, which are located in an increasingly vulnerable part of London’s Green Belt  (a protected area of green land around London and the home counties). This may include higher levels of protection, better protection from future development, and a better understanding of their role in sustaining London’s insect populations.
