Pond dipping

As I wandered around at RHS Harlow Carr Gardens near Harrogate recently, I noticed a school group busily engaged in exploring a pond. The children, about seven or eight years old, were enthusiastically dipping nets and seeing what weird and wonderful aquatic life was lurking among the water lilies. Mind you, listening to their excited squealing, it was amazing that all the creatures hadn't heard them and hidden themselves away!
