Longest butterfly migration
We now know the painted lady (Vanessa cardui) makes the longest migration of any butterfly: 9,000 miles from tropical Africa to the Arctic Circle, almost double the journey made by the previous record holder, the famed monarch butterfly.
It can take six successive generations of painted ladies to complete this epic journey, flying up to 1,500ft high and reaching speeds of 30mph. The butterflies that return to Africa at the end of the year are several generations removed from those that set out.
This astonishing and beautiful butterfly, spotted in the park for the first time last year, will begin arriving in Britain this month. Keep a look out for it.
