The famous painting - one of the most famous - by Constable, of Salisbury Cathedral from the water meadows, must surely be in the minds eye of many of us as we drive along the Harnham Road.

If you've not yet signed up for this and for full details, please go to Field Trips.
The pages now display photos of live moths taken by Andrew Graham. This one, the Puss Moth, looks very soft and cuddly.
