An expert has predicted a "bumper summer of butterflies" in Britain, following an unusually warm, dry spring and continuing hot weather that has favoured the insects. Prof Richard Fox, head of science at Butterfly Conservation in Newton Abbot, Devon, said the conditions have put butterflies "in a good place" to put on a colourful display in gardens and the countryside this summer, marking a potential rebound after a poor 2024.

Fox explained that as cold-blooded creatures, butterflies depend on sunshine to become active, mate and lay eggs, and species such as the Holly Blue and Red Admiral have already had a strong spring. However, he cautioned that the dry weather could threaten food supplies for caterpillars, as wilting plants and dying grass may leave the next generation short of food. He is encouraging people to take part in the Big Butterfly Count, which asks participants to record sightings over 15 minutes, to help determine how the season ultimately unfolds.
