Record numbers of Painted Lady expected in UK

The UK is braced for a once in a decade occasion as an influx of Painted Ladies are expected to arrive in the UK at any moment after unusually high numbers of the orange and black butterflies have been amassing in southern Europe.

The butterfly is a common immigrant that migrates in varying numbers from the continent to the UK each summer, where its caterpillars feed on thistles. But around once every 10 years the UK experiences a Painted Lady ‘summer’ when millions of the butterflies arrive en masse.

The last mass immigration took place in 2009 when around 11 million Painted Ladies descended widely across the UK with the butterflies spreading into the most northerly parts of Scotland. Since then the UK has experienced five years with below average numbers but scientists are hopeful that 2015 could be very different.
