Butterfly numbers in the UK appear to be at the lowest on record after a wet spring and summer dampened their chances of mating. This comes on top of a long and worrying trend of decline. To find out what’s going on and what we can all do to help butterflies cope with extreme weather patterns, Phoebe Weston speaks to Dr Richard Fox, the head of science for the charity Butterfly Conservation, and to Matthew Hayes, who is part of the Banking on Butterflies project, a collaboration between the Insect Ecology Group at the zoology department in Cambridge University and the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire.

Madeleine Finlay hears from the study’s lead author, Tim Stockwell, a scientist at the Canadian Institute for Substance Use Research at the University of Victoria, to find out why scientists (including him) were so convinced, and what the actual risks of alcohol are.
