A mass migration of Painted Lady butterflies is predicted for this summer, after large numbers of the migratory species have been sighted in southern Europe.
According to our partner organisation Butterfly Conservation, the warm sunny conditions on the continent have boosted numbers across the channel, meaning that the butterfly could be seen in large numbers in the UK for the first time since 2009.
Although the Painted Lady is a regular migrant to UK shores it cannot survive the winter here, with successive generations instead migrating back south as far as Africa when the weather cools. The numbers seen in the UK reflect the weather conditions further south, and can fluctuate widely from year to year, with large numbers being seen only once in 10 years on average.
Butterfly Conservation are keen to find out more about the Painted Lady and Hummingbird Hawkmoth, for more details please see the Butterfly Conservation Migrant Watch website.
