Description:

An example, albeit on a very small scale, of how human activities can help organisms move from place to place. The pictures show an Astrantia variety at the recent Malvern Spring Show. On the leaves are mines of the fly species Phytomyza astrantiae. The plant came from a nursery in Gloucestershire. The show draws in visitors from a wide area, so the plant had many potential homes. Such movements could help to explain the patchy distribution of the fly.
