One small snail. As a not very enthusiastic gardener I don't mind snails, I think that they are quite cute, and always rescue them from perilous positions (the side of my car, for example). My mother views snails as instruments of guerilla warfare and will happily throw them over fences!
It's that time of year... blue and green jewelled insects take to the air over the pond. Hard to catch as they rest only for moments before resuming their aerial dances.
Look very carefully! Some of the small brown fish that make up Jaw's retinue. Now the various pond treatments have worked there has been an enthusiastic return of the smaller fish.
