About the event

Tent mines, galleries, oak apples and spangles are just a few examples of leaf miners and galls.  On this course you learn will more about leaf miners and galls, experiencing “live” some of the more distinctive and even sometimes grotesque forms, and then put your new ID skills to the test.

In the morning there will be a presentation to introduce leaf miners and plant galls. The biology of these small and relatively little-studied yet fascinating organisms will be discussed, with hints given as to their identification and the ecological niches in which they may be found.

After lunch you will go out to study live material in the reserve, where it is anticipated many examples of leaf mines and galls will be found.  This will enable you to practise your newly-found identification skills and to appreciate the subtle beauty of this branch of “micro-nature”!

By the end of the day it is expected that you will:

  • Be able to identify some plant galls and  leaf miners and places where they can be found
  • Have an understanding of the biology of the organisms involved
